Wheat stubble straws are important factors influencing the seeding and production of next-stubble crops (summer corns), and in order to eliminate the influence of the wheat stubble straws on the crops, a plurality of farmers solve the problems by burning, generate larger damage on the surrounding natural environment and soil, eliminate the wheat stubble straws in time and also generate other influences on the growth of the crops. Wheat straw is an organic fertilizer, and if the organic fertilizer can be reasonably utilized, the organic fertilizer can provide rich nutrition for crops, so that the organic fertilizer is very favorable for agricultural production. However, if the stubble cleaning is carried out after wheat harvesting for blind purposes, some adverse factors also exist, such as influence on seeding, increase in planting cost, adverse effect on rainwater infiltration, delay of farming season and the like. Therefore, how to reasonably select whether to stubble ploughing to ensure the advantages over the disadvantages is a problem which needs to be carefully considered in agricultural planting.

Detailed Description
The invention relates to a method for determining straw stubble cleaning according to the ear number and the yield level of wheat, which is characterized in that the method comprises the steps of obtaining the ear number and the seed yield of wheat per mu of land to determine the biological yield of wheat straw, and when the biological yield of wheat straw is lower than 750-780 kg/mu, the stubble cleaning is not carried out after the wheat is harvested; when the biological yield of the wheat straws is (750-780) - (1100-1150) kg/mu, the wheat is sowed after stubble cleaning after harvesting; when the biological yield of the wheat straws is more than 1100-1150 kg/mu, the wheat is sown firstly and then stubble-cleaning is carried out after being harvested, and the method can scientifically guide whether the wheat straws are stubble-cleaning and the stubble-cleaning time.
The present invention will be further described with reference to the following examples.
In the following examples, the wheat and corn are planted in two cropping areas in one year, and preferably, when the biological yield of the wheat straws is less than 750 kg/mu, the wheat is not stubble-removed after harvesting; when the biological yield of the wheat straws is 750-1100 kg/mu, the wheat is harvested, stubble cleaning is carried out firstly, and then sowing is carried out; when the biological yield of the wheat straws is more than 1100 kg/mu, sowing the wheat straws firstly and then cleaning the wheat straws; the ear number per mu of wheat was measured during the growth period of wheat.
Whether stubble cleaning is needed or not is determined according to the wheat spike number and the wheat grain yield level, and finally the biological yield of wheat straws is determined, wherein the biological yield of the straws is lower than 750 kg/mu, so that the seeding and the growth of corns cannot be influenced, and on the contrary, the vertical straws are also beneficial to rainwater infiltration; the biological yield of the straws is 750-1100 kg/mu, and the straws are harvested, stubble-cleaned and sowed; the biological yield of the straws is more than 1100 kg/mu of wheat field, and the biomass of the straws is too large after stubble cleaning, which is not beneficial to normal sowing of agricultural machinery, so that the straws are sowed first and then stubble cleaning is carried out.
But the biological yield of the straws is inconvenient to count, the number of wheat ears can be investigated before wheat is harvested, and the yield of wheat grains can be weighed after the wheat is harvested, so that the method is convenient to operate and implement.
Taking weighbridge 4399 as an example, the average thousand-grain weight is 40g, the average ear grain number is 30 grains/ear, the economic coefficient is 0.4 (the economic coefficient of wheat varies from 0.3 to 0.5), and the single plant can be counted.
Seed yield: 30/strain × 40g/1000 particles =1.2 g/strain;
the yield of the whole plant is as follows: 1.2 g/strain/0.40 (economic coefficient) =3 g/strain;
the yield of the straws is as follows: 3 g/strain-1.2 g/strain =1.8 g/strain.
In example 1, 35 ten thousand ears per mu, the economic coefficient is the lowest (0.3), namely the straw amount is the highest, the biological yield of the whole field is 35 ten thousand ears/mu x 3 g/ear x (1-0.3) =735 kg/mu, which is close to or lower than 750 kg/mu, therefore, when the ear number is less than or equal to 35 ten thousand ears/mu, the highest biological yield of the straw can not exceed 750 kg/mu, therefore, the wheat planting in the test field is sparse, the yield does not need to be counted, and the stubble is not killed after the wheat is harvested.
Example 2, when the number of ears per mu is more than or equal to 35 ten thousand ears per mu and less than 38 ten thousand ears per mu, the total field biological yield (seeds + straws) is 1050-1140 kg/mu, the yield of the harvested wheat is counted, and when the seed yield is more than or equal to 400 kg/mu, the straw biological yield is: (1050-400) kg/mu- (1140-400) kg/mu, namely the highest biological yield of the straws is 740 kg/mu and less than 750 kg/mu, and the wheat is not stubble-cleaned after being harvested.
Similarly, in example 3, when the number of ears per mu is more than 35 ten thousand per mu and less than or equal to 38 ten thousand per mu, the yield of the harvested wheat is counted, when the yield of seeds is less than or equal to 400kg per mu, the biological yield of the straws is 750-1100kg per mu, and the wheat is sowed after stubble cleaning.
Example 4, when the number of ears is more than 38 ten thousand/mu and less than or equal to 48 ten thousand/mu, the biological yield of the whole field is 1140-1440 kg/mu, and the yield of the harvested seeds is more than or equal to 350 kg/mu, the biological yield of the straws is 750-1100 kg/mu, and the wheat is sowed after stubble cleaning.
Example 5, when the number of ears is more than or equal to 48 ten thousand per mu, the total field biological yield is more than or equal to 1440kg per mu, and the grain yield is more than or equal to 600kg per mu, the straw amount is less than 1440-600=840, and the method belongs to the field of wheat seeding after stubble cleaning. Estimating (the economic coefficient is generally not too high or too low and is stable when the yield per mu exceeds 600kg in the wheat field) according to the economic coefficient (0.35-0.45), wherein the yield per mu is 733-1116 kg/mu when the grain yield is more than or equal to 600 kg/mu and the total field biological yield is 1333-1716 kg/mu, and belongs to the sowing range after stubble cleaning after wheat harvest.
Example 6, when the number of spikes is more than or equal to 48 ten thousand per mu, the total field biological yield: 48 ten thousand per mu x 3 g/ear =1440 kg/mu, when the yield is less than 340 kg/mu, the straw yield is not lower than 1100 kg/mu, and the wheat is sowed firstly and then stubble-cleaning is carried out.
In the embodiment 7, when the ear number is more than 45 ten thousand/mu and less than or equal to 48 ten thousand/mu, the biological yield of the whole field is 1350 kg/mu to 1440 kg/mu, the grain yield is less than or equal to 350 kg/mu, the biological yield of the wheat straws is basically higher than 1100 kg/mu, and the wheat is sowed firstly and then stubble-cleaning is carried out after being harvested.
In the embodiments 3-5, the stubble cleaning is performed first and then the seeding is performed after the wheat is harvested, and when the stubble cleaning is performed first and then the seeding is performed, the land surface can be leveled after the stubble cleaning and before the seeding, so that the seeding and the field management are facilitated, and the seeding quality of the corn is improved. And (4) benefit comparison:
1. taking a wheat field without stubble cleaning as an example, if the stubble cleaning is carried out blindly, the benefit is-15 yuan/mu.
2. The benefits of stubble cleaning and non-stubble cleaning are calculated by taking the corn planted in the field needing stubble cleaning and without the harm of athetis lepigone and the corn seed yield of 600 kg/mu as an example:
(1) Stubble cleaning
The stubble cleaning cost is 15 yuan/mu; after stubble cleaning, the yield is increased by 10 percent compared with that of the stubble cleaning, namely the yield is increased by 60 kg/mu, and the pure benefit is 600kg multiplied by 10 percent multiplied by 1.6 yuan/kg-15 yuan =81 yuan.
(2) Without stubble cleaning
The method is characterized in that the harm of the athetis lepigone is generated when the corn is planted in the wheat field without stubble cleaning actually, the spraying cost of the athetis lepigone is 10 yuan/mu, the labor cost is 10 yuan/mu, and the two-point tailed leaf moths are seriously aged, after the harm is found, the two-point tailed leaf moths need to be prevented and treated for the second time, the cost is doubled, and the yield of the corn seeds is reduced by 10%. The benefits are as follows: -10-600 × 10% × 1.6= -136-yuan.
The income is increased by 136+81=217 yuan/mu compared with the stubble cleaning without stubble cleaning. Therefore, the stubble cleaning treatment is a technical measure of combining agricultural, mechanical and agricultural technologies with pollution-free green synergism in the wheat fields needing stubble cleaning.
The significance and the effect of stubble cleaning are as follows: 1. can provide a high-quality growing environment for the seedlings of the following corns and the like: in the early growth stage of crops such as summer corn and the like, the density of wheat stubble remained in soil is high, the photosynthesis of the corn can be weakened, the crops are weak and yellow due to lack of the photosynthesis, and in the early growth stage of the crops, under the action of wind, the wheat stubble easily cuts crop leaves, so that the exertion of the photosynthesis is restricted; 2. inhibiting the growth of weeds: the wheat stubble is eliminated, after the wheat stubble is blended into the soil, the illumination intensity on the surface of the soil can be effectively reduced, the photosynthesis of weeds in the soil is inhibited, the growth of the weeds is inhibited, crops can obtain more nutrients in the soil, the weeding effect is enhanced, and the growth of the crops is well promoted; 3. and (3) preventing and controlling athetis lepigone: after wheat is harvested, a stubble cleaner or shallow rotary tillage stubble cleaning is used, straw decomposition can be accelerated, and the harm of athetis lepigone is effectively reduced.
The wheat stubble with low density can reduce the cutting of crop seedling leaves, has good field permeability, is not beneficial to the oviposition of athetis lepigone, can reduce the insect pest of the athetis lepigone without cleaning the stubble, ensures the normal growth of seedlings and reduces the operation cost.
The method for determining straw stubble cleaning according to the number of wheat ears and the yield provides scientific guidance for the time when the wheat needs to be stubble cleaned and stubble cleaned in the planting process of the wheat and the corn, prevents the improvement of the operation cost caused by blind stubble cleaning, reduces the occurrence of the athetis lepigone insect pest, provides a good growth environment for the corn, and is beneficial to the improvement of the yield of the corn.
