The method for direct seeding rice in the shallow paddy field is easy and fast to operate, the seedling survival percentage of the broadcast rice seed buds is high, the drought resistance ability is strong, the flood control capability is strong, and the rice yield is high.

Description

The method of shallow water field direct seading rice

Technical field

what the present invention relates to is the scientific method of a kind of quick sowing paddy rice, belongs to agricultural technology field.

Background technology

The plantation of paddy rice is the pith that Chinese agriculture is produced, and paddy rice has large-area plantation at Central China and south, and rice cultivation has become the main source of China's grain.The plantation of paddy rice is the careful process of a complexity, the plantation of paddy rice comprises the sowing of paddy rice, the vegetative period of paddy rice nurses, the harvesting of paddy rice, and the type of seeding of paddy rice divides live formula and transplanting type, live formula comprises again the formula of sowing seeds and spreads bud formula, and transplanting type comprises seedling throwing type and rice transplanting formula.In all types of seeding of paddy rice, rice transplanting formula is the most miscellaneous difficult type of seeding, but rice transplanting formula can be carried out in the very dark paddy field of water, and alternate manner but can not have such anti-flood capacity; Seedling throwing type also has certain anti-shallow water ability, but the breeding process of rice transplanting is also very miscellaneous, and the rice shoot under just throwing runs into rainy, current will be flushed away destruction; Loose kind of formula the most fast, seed is directly spread field by formula of sowing seeds exactly, but the seed germination rate under spreading is very low, and seed germinates the time needing several days in the ground, in the time in the past few days, seed can not may be germinateed by sun insolation, and the skim moisture submergence caused of may being rained is gone bad; With the formula of sowing seeds almost the same method of rice growing be fast spread bud formula, spread bud formula and have certain initial stage anti-flood capacity and drought-resistant ability, and survival rate and the seedling throwing type of planting bud are made no distinction of rank, the rice growing method of therefore spreading bud formula is the good method being worth research, exploitation, popularization.

Summary of the invention

in order to simplify rice growing a series of numerous and diverse operation, in order to save time, also in order to improve the output of paddy rice, the method of a kind of rapid rice sowing of my invention: the method for shallow water field direct seading rice, makes to sow in this way that paddy rice anti-flood capacity is large, drought-resistant ability is strong, output is high.

the art scheme that the method for shallow water field direct seading rice is taked is: one, and seed infiltrates in advance to germination; Two, shallow water field ploughing is to level and one deck mud is played on surface; Three, have suffered dispenser fertilizer in journey the cultivated of paddy field; Four, and then water field ploughing is complete broadcasts sowing kind of a bud; Five, control the water yield after broadcasting sowing and the sprinkling carrying out weed killer herbicide.

one, the method for shallow water field direct seading rice is germinateed in the infiltration that first three day of sowing must carry out seed.The infiltration of rice paddy seed is germinateed and must be had a rigorous method process, and not observing this method will destroy seed: 1. first divided by seed and put in woven bag, about 7 kilograms of seeds use a textile bag, and woven bag must be permeable, ventilative; 2. put in clear water soak filling seed-bearing woven bag, the clean fresh water of described clear water preferably mobility, in water, opened braiding have gentle hands stir seed carry out cleaning seed every 4 hours, put into again after half an hour of leaving the water after cleaning in water and continue to soak, like this repetition 3 times; 3. leaving standstill the seed infiltrated being continued to stay in woven bag, time standing, pinioning sack, make inner dark, temperature rising, be conducive to seed sprouting; 4. in leaving standstill, temperature constantly raises and can injure kind of a bud, therefore within every 3 hours, woven bag will be put in water and careful rinsing cooling will be carried out to seed, rinsing also makes seed again obtain supplementing of moisture, again braiding is relay after rinsing and leave standstill in atmosphere, so repeatedly until seed sprouting is about 0.5 centimetre for best to length broadcast sowing the phase.If because weather or other reason can not be broadcasted sowing the suitable seed that germinates on time, plant bud can continue to increase, the kind bud increased produces very large air drag when broadcasting sowing, and plants bud and also mutually can hook to pull to cause and broadcast sowing uneven, also to produce kind of the bud that fractures probability.

two, shallow water field cultivated whole.The drought resistance of spreading bud formula rice growing method is the thing after planting, but must carry out in the field having water during sowing.Paddy field must be whole to level, and this farming for mechanization is not problem, if harrow farming with Niu Li, finally strikes off face, field with parallel wood.

three, the dispenser of fertilizer must carry out in the cultivated whole middle time-out in paddy field, just broadcast application of trying not after sowing seeds, because face, field can be made to produce more footprint, and has fertilizer grain and touches nearly seed and just become injury.

four, paddy field cultivated whole in, rice seedling has been ready to be placed on limit, field in advance, ploughs whole complete at once and then carrying out and broadcasts sowing kind of a bud, and because of mud is at this moment the abundantest, firmly, but bud point will soon stretch out the mud bag pressure that the seed under spreading can be precipitated.

five, the water rate control after broadcasting sowing: the water yield should keep can not submergence seed bud point because seed also needs respiration, because of quick-fried rain, submergence bud point should draining as early as possible.The sprinkling of weed killer herbicide should be carried out after broadcasting sowing three days because the seed resist ability just broadcasted sowing is also very weak, weed killer herbicide to press down the weed killer herbicide of careless bud, during spraying herbicide should with sow seeds bud time the footprint walking that produces.

the beneficial effect of the method for shallow water field direct seading rice is: the method for shallow water field direct seading rice make rice growing fast, simple and plant bud and turn that high, the anti-leaching drought-resistant ability of root planting percent is strong, output is high.

Embodiment

one, the infiltration of seed is germinateed: peasant household must carry out the selection of seed according to the character in field, and some rice varieties drought resisting abilities are strong, and the anti-immersion ability of some kinds is strong, carries out seed soaking germinate for subsequent use after have selected seed by the precise procedures of seed soaking; Two, take limit, field by germinateing to the seed of about 0.5 centimeter length and prepare and carry out the cultivated whole of paddy field, this preparation will in the morning or noon, not plough behind whole good field darkness in the afternoon, extensive cultivation or thin cultivated can, but finally paddy field must voltage levels; Three, suspend in the process of farming and carry out the dispenser of fertilizer, fertilizer based on urea, with a small amount of potassium chloride, about 8 kilograms, every mu of urea, 2 kilograms, potassium chloride, too much fertilizer suppresses seed to turn root growth on the contrary; Four, and then the firm farming in paddy field is complete carries out broadcasting sowing of kind of bud, must not smoke and have a rest in midway (unless there are people's changing shifts), the speed of walking and the kind bud quantity of broadcasting sowing will be controlled well when broadcasting sowing, the seed that can control to fall about 40 at every square metre is for best, a people can broadcast sowing more than 6 mu in 2 hours, really saves many artificial; Five, water rate control after broadcasting sowing, the water yield after broadcasting sowing can not the bud point of submergence seed be limited, preferably can reduce Soil surface water to divide earth is exposed, such earth can harden very soon and to be fixed very soon by foundation kind bud loosely, and the firm like this kind bud broadcasted sowing also can resist washing away of heavy rain or temporary transient flood attacks; The sprinkling of weed killer herbicide should be broadcasted sowing after three days and be carried out, and at this moment plant bud foundation and fix, the weed killer herbicide of recommendation is 96% molinate missible oil, fourth Benzyl wetting powder, benzyl dichloride wetting powder, and strict illustratively consumption executes spray.
