Introduction: As an important food crop and feed crop in China, the planting technology of corn has always attracted much attention. Today, we will reveal a magical planting technology for you - corn mulching cultivation technology, so that your corn yield per mu can be doubled!
1. How much mulch does it take to plant one acre of corn?
According to the experience of farmers and growers for many years, if corn is planted in wide and narrow rows, the big line is 10 meters, small rows 04 meters, with a width of 80 and a thickness of 05 filaments of mulch to cover, the amount of mulch to be used is about 1About 9 kg.
2. Why do corn fields need mulch?
1.Warming and insulation: The average daily temperature of the 5 cm deep soil layer of film-covered corn during the whole growth period is 1. higher than that of the open-field corn field5—2.5 degrees Celsius, more than 10 degrees Celsius, the active accumulated temperature increases by 200-300 degrees Celsius. Especially during the period from sowing to emergence, the warming effect is obvious, which creates conditions for early sowing and early emergence.
2.Moisturizing and drought prevention: Mulching can prevent the direct loss of surface soil moisture. Increasing the moisture content of surface soil has the effect of drought resistance and moisture preservation. According to the measurement, the soil moisture content can be increased by 3 -5 in drought and up to 10 in high time, which is conducive to maize emergence in arid areas.
3.Improve soil physical and chemical properties: mulching creates favorable conditions for soil microbial activities, such as water, temperature, aeration, etc., which can promote the activity and reproduction of microorganisms, improve the activity of various soil enzymes, accelerate the effective process of soil nutrients, improve the fertilizer supply capacity of soil, and lay a good soil foundation for the growth and development of soil rice.
4.Promote the development of corn and mature early: mulching cultivation can generally make corn emerge 5-7 days early, about 10 days early to tassel, and 10-15 days to mature early. This allows you to take advantage of the limited growing season and avoid the unfavourable influences of Gonso.
5.Yield improvement traits: The relationship between water, air and heat in the soil is coordinated by plastic film mulching. It promotes the growth and development of maize roots, so that the aboveground growth is robust, and at the same time, it can improve the economic traits of maize and increase the yield.
After reading this article, I believe you have a deeper understanding of corn mulching cultivation technology. This technology can not only increase the yield of maize, but also improve the soil environment and contribute to the sustainable development of agriculture in China. If you're still worried about low corn yields, try this growing technique! Double your corn production and get on your way to riches!
