Corn is an important autumn crop grain crop in China, corn production has important significance for the feed and food processing industry, and the high and stable yield of corn is influenced by lodging, diseases, extensive fertilization technology and other reasons in the field production of corn;

at present, farmers in corn production areas have no systematic disease prevention and nutrition medication habits, generally only spray shrinkage products in a large trumpet period or use certain leaf fertilizers and pesticides according to the recommendation of dealers, so that the side effects such as baldness and pointedness are easily caused, the yield reduction and yield increase effects are not ideal, and the main problems in corn production are as follows:

1. no system management concept exists, and the consciousness of preventing diseases is not strong; if rust disease is outbreak in the later period of the corn, the consequences are unreasonable, the corn is a high-stalk crop and is difficult to prevent and control in the later period, large-area yield reduction is caused, and losses of farmers are serious;

2. the medication time is random; disease prevention and nutrition medicine application consciousness is desert, key nodes of the growth cycle of the corn are not used or not used, and the yield increase potential of the corn is not fully developed;

The following describes the beneficial technical effects of the present invention in detail through data:

the test was divided into three groups of treatments:

a: this scheme medicament

B: conventional administration (conventional administration CK2)

C: clear water contrast (CK1)

The application time and the application method are as follows:

spraying at seedling stage (first time)

Spraying in the big horn mouth period (second time)

Selecting sunny and windless weather, spraying the pesticide after 5 pm, performing covering and adjacent treatment during pesticide spraying to prevent pesticide drift, uniformly preventing and killing weeds in field management, uniformly preventing and controlling pests, performing other management according to a high-yield field management technology, respectively sampling and collecting the peanut yield in three groups of same area areas when harvesting, and then converting into acre yield according to the sampling area;

the results of the different treatments on the yields are analyzed as shown in the following table:

(1) analysis of the results of the different treatments on yield:

from the test yield structure, the ear number per mu, ear number per grain, hundred grain weight and yield per mu of the group a (the present formulation) were all the highest, wherein the group a increased 66.8% (309.8kg) compared to CK1 (clear water control) and 32.6% (190.4kg) compared to CK2 (conventional application), wherein CK2 (conventional application) increased 25.77% (119.4kg) compared to CK1 (clear water control), as can be seen from the above table: compared with conventional pesticide application and clear water control, the pesticide spraying on the peanuts according to specific time (spraying at the seedling stage and large horn mouth stage) can achieve a relatively obvious yield increase effect;

(2) results analysis of ear height for different treatments:

from the test yield structure, the height of the ear position of the group A is reduced by 5.1 percent (5.5 cm) relative to that of CK1 and CK2, the heights of the ear positions of the group A and the group CK1 are the same as that of the ear position of the group CK2, and the ear position height of peanuts is obviously reduced relative to that of conventional pesticide application and clear water control by spraying the pesticide of the scheme on the peanuts within a specific time (a seedling stage spraying mode and a large flare stage), so that the lodging resistance of the peanuts is obviously enhanced;

(3) analysis of results for spike size for different treatments:

from the experimental yield structure, the number of ear grains in group a was increased by 42.2% (182 grains) relative to CK1 and by 22.1% (111 grains) relative to CK2, which can be derived from the data: the grain number of the corn ear applied conventionally is increased relative to that of a clear water control group, and the grain number is increased more obviously relative to that of the corn ear applied conventionally by spraying the agent of the scheme on the peanut in a specific time (spraying in a seedling stage and a large flare stage).
