Plastic Film mulching Technology of Maize with large ridges and double rows

Maize with large ridge and double row plastic film mulching is an advanced cultivation technique which can improve the utilization rate of light energy and water and fertilizer, increase the accumulated temperature and significantly increase the yield. This technique is suitable for the main corn producing areas of our province, especially in the arid areas of the west and the semi-mountainous areas of the east. It is understood that this year, our province plans to popularize the cultivation technology of "big double mulch" in the main corn producing areas of 5 million mu, and plans to increase production by 25%.

Relevant agricultural experts introduced the main technical points: select plots with flat, deep, medium or above fertility and good drainage and irrigation conditions, and pay attention to soil moisture conservation; plastic film mulching cultivation due to suitable temperature and humidity, the occurrence of underground pests is relatively serious, seed coating agent should be used for seed coating before sowing; fertilization should achieve the combination of agriculture and chemical fertilizer, and do a good job of balanced fertilization of nutrients. In particular, the amount of nitrogen and potash fertilizer should be sufficient to avoid late de-fertilizing and premature senescence; the planting density can be increased by 5% Mur10% depending on the variety compared with ordinary planting methods; chemical herbicides should be used to seal the soil in time after sowing to eliminate weeds; when mulching, attention should be paid to prevent excessive soil pressure affecting light transmittance, lax soil pressure, loss of soil moisture and windswept film.

According to the measurement of agricultural experts, the corn planted with large double mulching technology is about 30 centimeters higher than the corn planted in the common way. Experts suggest that with the improvement of the current mechanized cultivation of maize with "big double mulch", farmers should apply this technology to the whole process of corn planting.
