Key points of cultivation techniques of dry cultivation and sparse planting of planting Rice

According to the characteristics of high yield, the cultivation technique of dry cultivation and sparse planting of rice is based on the application of comprehensive cultivation techniques to promote rice to achieve strong seedlings, healthy plants, long ears, full ears, many grains and full grains in the process of growth and development, and finally achieve high yield, low consumption and high efficiency. a technology to achieve high yield and high yield. The main cultivation techniques are as follows:

1. dry cultivation and cultivation of strong seedlings in fertile beds

The seedling cultivation technique has the advantages of wide adaptability, good seedling quality, large elasticity of seedling age, strong stress resistance, quick transplanting and obvious yield increasing effect. generally, the yield per mu is more than 10% higher than that of other seedling raising methods.

Second, shallow insertion

Shallow planting in shallow water is required, and the planting depth is not more than 3 cm, so the whole field is required to be of high quality, so that the field is flat and muddy, achieve early growth and rapid development, and promote low tillers into ears.

Third, sparse planting

The number of planting clusters per mu is less than that of other seedling raising methods, and the specific degree of sparse planting depends on varieties, stubble and soil fertility. generally, the tillering ability of general varieties is weak, the field fertility is low, the planting density is dense, the tillering ability of varieties is strong, the field fertility is high, and the planting density is sparse. It is appropriate to adopt standardized single-row strip loading, which requires a transplanting density of 1.8-22000 clumps per mu and 5-75000 seedlings per mu.
