Embodiment 1

[0040] Embodiment 1, Chinese yam (yam) cultivation. Hosted by researcher Wei Benhui of Economic Crops Research Institute of Guangxi Academy of Agricultural Sciences, the inventor, based on the experience gained from the experiments in Nanning City, Guangxi and Wuming County, respectively, large-scale contiguous planting experiments in Nanning City, Guigang City, and Beihai City, Guangxi, Adopt drill-type rotary tillage and spiral-type mechanical farming to plant Huaishan. The ditch depth H is 80 cm-100 cm. The soil layer at the bottom of the plow is turned up, and the silt is formed into ridges. The silt distribution is in a "T" shape. It is used in deep ditching to automatically stack silt into ridges. The deep ditch in the ridge is 90 cm wide and 30 cm wide. The silt suspended in the ditch will automatically form a trapezoidal ridge on the ground. The width A is more than 60-70 centimeters; among them, at the implementation base of continuous planting in Wuming County, Nanni...

Abstract

The invention discloses a method for planting dryland crops. A rotavator is utilized to deeply loosen and crash the soil in furrows so as to crash the loose soil in a cultivated layer and plough sole and make a portion of foreign soil in the plough sole rise up to be naturally mixed with the soil in the cultivated layer for forming furrows and ridges. The ridges are trapezoidal. Each furrow is 25to 30 cm in width and 80 to 100 cm in depth with loose soil distributed in a T shape, and each loose ridge can be 70 to 80 cm in width and 20 to 25 cm in height; or, each furrow is 50 cm in width and60 to 70 cm in depth, and each ridge is 90 cm in width and 20 cm in height. Crops can be planted right after soil is loosened by the rotavator and formed into ridges. Spacing and furrow depth can be determined according to the planting requirements of different crops. By using the method of the invention, soil in the whole cultivated layer is in a loose state, and foreign soil can be improved during deep rotary tillage, therefore, the water and fertilizer retaining ability and the permeability of the soil are enhanced. The invention has the advantages of helping crops root deeply and utilize water and fertilizer, relatively reducing diseases and weeds, and greatly increasing the yield of crops (usually over 20%, and a maximum of over 100%).

Description

technical field [0001] The invention relates to a cultivation method for crops, in particular to a cultivation method for dryland crops. Background technique [0002] Looking back on China's agricultural history for thousands of years, from slash-and-burn farming to human-powered land preparation and animal-powered plowing and harrowing, the current farming method of mechanical plowing and harrowing is a very mature technology. Different crops use different farming methods, and it seems that there is no longer research. According to the written records of ancient books, people have long realized that farming methods have a very important and inevitable relationship with high-quality and high-yield crop growth. For example, the Daitian method and the district-based method that became popular in the middle of the Western Han Dynasty came about in response to the land continuous cropping system. In order to facilitate the restoration of soil fertility, the replacement land syst...
