Summer corn enters the grain-filling stage. In order to promote good grain filling of the corn and ensure that the seeds are full and full, it is truly a good harvest. I, as a technical instructor, combine my own technology demonstration villages, go deep into the fields and do a good job of technical guidance.
1. Make full use of the sun light. The main goal of the filling period is to preserve the roots, protect the leaves, prevent premature aging of the leaves, and promote corn grain and grain weight to achieve high yields.
2. Focus on water and fertilizer management. Due to the long grouting time of summer corn and the accumulation of dry matter, the amount of water and nutrients needed is also large. Should rely on fertility conditions, as appropriate, follow-up attacking granulation fertilizer (mainly available nitrogen fertilizer-based) to meet the nutrient needs. At the same time, it is necessary to strengthen water management. Maize has a large demand for water during the grain filling period and it is more resistant to flooding.
3. Strengthen field management to prevent falling production. The lodging of corn in the middle and late stages is the main factor limiting the yield increase of corn.
4. Conduct cultivator cultivation. In the late stage of grouting, we should also cultivating once in shallow soil, ventilate loose soil, ensure weeding, prevent weeding, and also facilitate decomposition of nutrients, promote root absorption, prevent premature aging of leaves, and increase grain weight.
5. Timely pest control. Corn corn borer, armyworm, cotton bollworm, aphids, and other hazards are common during corn filling, and care must be taken to prevent and control it. Http://
