1. The correct selection of good varieties and the selection of hybrids with high potential for high yields can be sowed in due time and planted locally.
2. Improve seeding quality Use new single-grained on-demand machines and appropriately increase seeding capacity to ensure Miao Qi, Miao Quan and Miao Zhuang.
3, improve the lighting conditions within the group
First, according to the characteristics of species, soil fertility and cultivation levels to implement a reasonable close planting, and second, to take ribbon, sets of planting, in order to improve the population of the upper light conditions.
4. Strengthen fertilizer and water management Adhere to the fertilization principle of “applying basic fertilizer, lightly applying Miaofei, skillfully applying stalk manure, vigorously attacking panicle fertilizer, and discretionary application of grain fertilizer†to achieve the application of nitrogen, phosphorus, potassium and organic and inorganic fertilizers to meet The overall demand for nutrients during various growth stages of corn.
5. Timely irrigation and drainage The large bell-mouth and silking stage of corn are the critical period of water requirement. When drought occurs, watering should be done in time to maintain field water holding capacity of 70-80% to promote the differentiation of male and female spikes and the formation of tassel pollen. development. At the same time, the flowering period of spring maize is in the rainy season, and extremely anomalous weather such as heavy rain is very easy to occur. In case of encountering locusts, water accumulation should be promptly eliminated to promote the normal growth of corn.
6. Advocate artificial pollination and intercalation Artifically assisted pollination is an effective measure to meet the need for pollen, baldness, and lack of grain in the ear. Detasseling can play a role in reducing nutrient consumption, promoting coordination between males and females, reducing caries, and increasing yield. However, in the event of continuous rain or high temperatures, it should not be emasculated.
7. Pay attention to the prevention and control of pests and diseases In the middle and later stages of corn, comprehensive prevention and control of large and small spot diseases, sheath blight, corn borer, aphid, and other pests should be done in a timely manner to ensure normal growth and development of corn ear.
In the corn production, to achieve the above seven points, we can effectively prevent corn empty stalks, bald heads, lack of grain, so as to achieve the purpose of high yield.
