Master the best time for corn spray control and spraying agent
In recent years, China's pesticide industry has developed rapidly and has improved significantly in all aspects. However, there are still many factors that restrict the healthy development of the pesticide industry. In the case of corn crops, strengthening farmers' awareness of pesticides and the optimal spraying period of corn is conducive to better growth of corn. The term housewares encompasses an array of items that outfit a home. Some of these items may be essential, such as cooking utensils in the kitchen, while others are more decorative in nature such as fancy window treatments and wall hangings. The purchase of housewares for a home can be a never-ending process as new appliances and gadgets are introduced to the market every day.Housewares can be as basic or elaborate as your design wishes allow.

After entering the summer, due to a lot of lightning weather, corn is easy to blow, so in order to prevent the corn from lodging, many farmers will spray the control agent to the corn. When does the control agent have the best effect?
Why should corn be sprayed with corn control? The amount of fertilizer needed for corn seedlings is small, and the amount of fertilizer needed in the later stage is large. According to the fertilizer requirement of corn, fertilization of high-yield corn should be based on topdressing. Therefore, corn experts put forward that corn fertilization should be “one high, two chasing the waist, three chasing the bare hairâ€, that is, in the corn seedling stage, In the big bell period, the initial stage of silking is divided into three times. But the reality is: the main rural laborers go to work in the cities, and the farms are all "old, weak, sick and disabled". The "employed workers" are costly. In addition, the corn plants are tall and the topdressing is difficult. It is necessary to "simplify fertilization", that is, "fertilizer and sowing". Not topdressing. However, the problem of "fertilizer and sowing" without topdressing is: the seedling stage "nutrition is overslept, the stem grows too fast, resulting in a long internode of the corn curtain, weak stems, no lodging resistance, middle and late "nutrition Poor, the ear is small, empty, bald, affecting the increase in corn yield.
Spraying at the 6-10 leaf stage of corn, one can shorten the internodes of the corn base, increase the "overlord root", reduce the height of the ear, and effectively prevent the lodging of corn; the second is to reduce the consumption of nutrients in the corn seedling stage. To save nutrients, ensure the nutritional needs of the late corn, and coordinate the contradiction between “simplified fertilizationâ€, “fertilization of seed and fertilizer†and high yield of fertilizer in corn, avoiding the phenomenon of empty trees, baldness and “old pigeon headâ€. The best time for corn to increase production of 15-20% corn spray control agent is the best use period of corn control agent is corn 6-10 leaf stage, that is, corn "foot high" to corn "knee high", this period is In the early stage of jointing of corn, the corn stalks can be thickened after the spraying, the internodes are shortened, the height of the ears is reduced, and the number of layers and the number of "overlord roots" are increased, which can effectively prevent the lodging of corn and promote the nutrient to the ear. The operation of the department reduces the number of empty trees and baldness. Corn is less than 6 leaf stage using the control agent, the mountain is controlled too early, causing the corn to be weak and the stem is too low, so it is recommended to apply after the 6-leaf stage. The corn control agent is used too late, the number of leaves exceeds 12 pieces, and the corn has passed the jointing stage, which will cause the following problems:
The best time for corn sprayed to control the prosthetic agent 1. Incorrectly shrinking the corn: It should have shortened the base 1-3 internodes, but now it causes the middle 4-5 internodes to get the 1-3 internodes. Shortening, not only can not effectively prevent the lodging of corn, but also lead to poor growth of corn, resulting in reduced corn production in the later period;
2. Affecting the differentiation of corn tassels: After the jointing, the tassels of the corn begin to differentiate. If corn growth is controlled at this time, it will affect the differentiation of corn tassels, resulting in less pollen of corn scorpion, which will affect the pollination of corn and finally affect the yield of corn. Therefore, corn control must not be too late.
