Method of cultivating rice and rapes by applying double cropping straw to farmland

Abstract

The invention discloses a method of cultivating rice and rapes by applying double cropping straw to a farmland, comprising the following steps: (1) digging rape ridges;(2) applying base fertilizer in rows; (3) planting rapes; (4) applying the straw to the farmland; (5) heapping the rapes; (6) managing rice stubble rape field; (7) harvesting the rapes; (8) burying channels of the rape ridges and the like. By using the invention, row distances of ridge surfaces of directly planted rapes and transplanted rapes are respectively enlarged to a strap of 60cm and the straw totally applied to the farmland can be contained between the rows, thereby being beneficial to development of heapping the rapes; and a furrow with the width of 40cm reaches a depth of 20-25cm below a farmland surface so that the rapes totally applied to the farmland can be fully contained in the furrow, thereby solving the difficult problem of applying the straw to the farmland.

Description

technical field [0001] The invention relates to a farming method for planting winter rapeseed in a rice stubble and returning the full amount of straw that is ripe twice a year to the field. technical background [0002] Planting winter rapeseed after rice harvest is an important stubble layout for agricultural production in my country. Farmers know that it is good to return straw to the field, but it is more difficult to return second-ripe rice and rapeseed straw to the field. Because the rapeseed is planted in a square hole of about 30cm, the straw cannot be returned to the field. In order to solve the problem of straw returning to the field, the row spacing of hole planted rapeseed is expanded, and the density is too thin to affect the yield per unit area. It should be easier to return rapeseed to the field after harvesting, because most of the short vegetables are returned to the field on the shallow surface of the field, which not only affects the plowing and harrowin...

AI Technical Summary

Problems solved by technology

[0015] The purpose of the present invention is to overcome the shortcomings of rice stubble and rapeseed square hole planting that straw cannot be returned to the field, and shallow vegetable chess in furrows cannot be buried in ditches, and provide a kind of rapeseed that can expand row spacing, reduce plant spacing, and deep ditch to block vegetables in time after rapeseed is planted. The rice and rapeseed double-cooked straw returning farming method realizes the circular agriculture of returning the rice straw and vegetables to the field in full
