Method for planting potatoes in cotton board field

Abstract

Disclosed is a method for planting potatoes in cotton board field. The method includes: stem and weed pulling and removing, cotton stem crushing and fermenting, seed selecting and cutting, seed laying and covering, seed covering and filming, film uncovering and seedling selecting and seedling digging up and potato picking. The method is concise and convenient in operation and laborsaving and energy saving, and yield and efficiency are increased; 3 kilograms of zinc fertilizer is applied per mu, zinc content is increased by 1.93 milligrams every 100 grams of the potatoes, convenient, reliable and safe food is provided for people with zinc supplement; resistance and cold-resistant rate of potato seedlings can be increased by applying 2 kilograms of monopotassium phosphate per mu; by fully returning cotton stems and straws to the field, the problem about piling in disorder is solved, soil structure is improved, and soil organic matter is enhanced; manual labor strength is alleviated to the greatest extent by planting the potatoes in the cotton board field, quality of agricultural products is improved, effect of farm lands is increased, and the problem about how to select to plant winter crops after harvest of cotton is solved; by the adoption of filming, temperature is regulated, moisture is kept, and early mature and fast growth of the potato seedlings are promoted; with cotton stem powder covered, potato piece stems are favorably expanded without being squeezed, the potatoes are easy to grow, and potato skin is smooth and oily.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for planting potatoes in a cotton field. Background technique [0002] Potatoes are used for food, economics, feed, and industrial raw materials. China is the largest potato producer in the world, accounting for about 1 / 4 of the world's total area and total output. The area of ​​winter fallow fields in southern my country is large, and the potato planting area only accounts for about 5% of the country's total. The development potential is huge. Winter planting potatoes have become a new hot spot in agricultural development in southern China. With the abolition of the national cotton purchase and storage policy, the benefits of cotton planting are low, and cotton production continues to show a downward trend. Although the rotation of rapeseed, wheat, potato, etc. and cotton can alleviate the land competition for grain (oil) and cotton, increase the multiple crop...

AI Technical Summary

Problems solved by technology

This method is not only cumbersome and tiring, labor-intensive and time-consuming, but also the potatoes are squeezed by the soil when the tubers expand in the soil, which is not conducive to the expansion of the tubers, making the tubers relatively small, the rate of large and medium-sized potatoes is very low, and the potato skin is not smooth. Oily, digging the soil to look for potatoes will cause great damage to the potatoes, either missing heads or broken waists

In addition, the straw is not piled up randomly, or it is set on fire and burned. The straw is not used, which causes great pollution to the environment and brings safety hazards to people's lives and property.
