Vertical deep-rotation cultivation method for potato in semi-arid region

Abstract

The invention discloses a method for a vertical deep-rotation cultivation of potatoes in a semi-arid area, which comprises the following steps of: 1) land selection and pretreatment;2) application ofbase fertilizer: apply organic fertilizer and chemical fertilizer along with the vertical deep-rotation; 3) vertical deep-rotation and ridging: with depth of 35-40cm by vertical deep-rotation, dig deep ditch between large ridges , and small groove on the middle of the large-ridge; 4) cover of auxiliary materials and film; cover the ridge surface and the groove surface with the corn cob powder andthe wheat shell, and then cover the whole surface with black film, and place fine soil on the upper film surface of the ridge; 5) seed selection and seed treatment; 6) sowing; 7) field-management; 8)prevention and control of plant diseases and insect pests; 9) timely harvesting; 10) removal of the waste film. The method can be used to improve the quality and yield of potatoes, increase the production efficiency and improve the economic benefit, and is applicable for large-scale cultivation and transplantation. The test shows that the yield of the potato planted by the method is increased by 12.7% on year-on-year basis, in particular, the commodity rate is increased to 75.3%.

Description

Technical field [0001] The invention belongs to the technical field of crop cultivation, and specifically relates to a potato vertical deep rotary tillage cultivation method in a semi-arid area. Background technique [0002] Potato, wheat, rice, and corn are the four important food crops. Among them, potato has the highest protein content per unit area under the same planting conditions, and the protein molecules contained are easily absorbed by the human body. In addition, potatoes also contain carotene and ascorbic acid that other food crops do not have. Potatoes are rich in nutrition and have a reasonable composition structure. They contain 4 times and 10 times the VB and VC of apples, and the content of other minerals is more than 10 times that of apples. In daily life, foods processed with potatoes as raw materials are particularly popular. Nutritionists call potatoes a cost-effective food. Potatoes have always been an indispensable and important raw material in the proce...

Problems solved by technology

But generally 30-40cm is the bottom of the plow. If the bottom of the plow is not broken, it is not conducive to the root system of the crops, especially not conducive to the expansion of the tubers of the tuber crops, which will affect the increase in yield.

In addition, the depth of fertilization is shallow, which is not conducive to the full absorption of crops.
