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. Therefore, high temperature, drought, and even cloudy days are not conducive to the formation of grain yield during grain filling. Appropriate temperatures, lyrics, and sufficient sunlight are favorable for grouting.
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, we must strengthen water management. Maize has a large demand for water during grain filling, and it is more tolerant to flooding. However, if there is water accumulation in the field, it must be drained in a timely manner to ensure the absorption of root system to prevent loss due 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. In the case of planting dense-resistant, lodging-resistant varieties, reasonable dense planting, reasonable fertilization, medium-tillage cultivation, timely removal of small and weak empty plants, etc., if excessively dense plots with serious risk of lodging are discovered, plant growth regulation can be applied in advance. Agent.
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.
Why choose aspheric lens?
Aspherical lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design.
Our aspheric lenses are made by grinding & polishing. So they are more precise than traditional mould pressed. And also the tooling cost for grinding & polishign would be cheap and small quantity order would be accept.
