High-yield cultivating method of corns

Abstract

A high-yield cultivating method of corns belongs to agriculture and overcomes the shortcoming that an existing planting method is difficult in continuing to increase yield. The high-yield cultivating method of the corns comprises performing deep scarification of furrows at intervals one by one on ridged cultivated land, and applying farmyard manure in a deep scarification layer while performing deep scarification, watering in the furrows after deep scarification and fertilization, sowing seeds in the watered furrows, paving straw in the furrows where the straw is cut in autumn harvest, in the next year performing the deep scarification, fertilization, watering and seeding cultivation in furrows which are idle in the last year, idling the furrows where the seeds are sown and the straw is paved, repeating the cycle, and forming the law that cultivation is performed to each furrow every other year, namely performing alternate cultivation to adjacent furrows on an annual basis. The high-yield cultivating method of the corns has the advantages of water retention and duration of soil fertility-keeping ability. Crops are good in light transmission and ventilation, deep in root system and resistant to lodging. The straw returning to the field keeps warm, preserves soil moisture, resists soil loss and is high in corrosion utilizing rate. A process of stubble cleaning cultivation is omitted. On the premises of saving energy and labor input, the high-yield cultivating method can obviously improve unit area yield of the corns and improve quality of corn kernels.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to corn planting. Background technique [0002] Throughout the ages, improving crop yields is inseparable from variety improvement, soil fertility improvement, and reasonable dense planting. At present, the close planting of corn, an important food crop, has reached 45,000 plants. The commonly used planting pattern is planting on ridges. Due to the requirements of light and ventilation and the factors that have emphasized the decline of soil fertility over the years, especially the deterioration of the natural environment and the decrease of precipitation, the current planting density can no longer allow the normal growth of large-eared varieties. According to the current domestic planting technology, it is difficult to increase the yield of corn significantly before the emergence of new high-yielding varieties. The introduction of technologies such as soil improvement for ...

AI Technical Summary

Problems solved by technology

According to the current planting technology in China, it is difficult to increase the yield of corn by a large margin before the emergence of new high-yield varieties.

The introduction of agricultural technology developed countries to maintain and improve soil fertility, rational and full use of water and fertilizer technologies, etc., still have shortcomings such as high cost, difficult use and management, and unsatisfactory economic benefits.
