Method for quickly desalting, dealkalizing and ploughing soda saline-alkali paddy field

Abstract

The invention provides a method for quickly desalting, dealkalizing and ploughing a soda saline-alkali paddy field. The method comprises the following steps of: in the rice field after rice harvest in autumn, turning up the soil by using a big plough in autumn after base fertilizer is applied; sunning the upturned soil; rotating the soil in a dry mode in spring of the next year; ridging and soaking; leveling the field by using a thick rake until slurry is settled; and transplanting. In the method, spring soil turnup is replaced by autumn soil turnup; autumn soil turnup is combined with springsoil rotation; advantages of two tillage methods of rotary tillage and autumn soil turnup are utilized, advantages are absorbed and disadvantages are complemented, advantages are utilized and disadvantages are avoided, soil fertility is adjusted, and soil application and improvement are taken into consideration; and water resource is saved, saline and alkali are removed quickly, the soil structure is optimized, fragile ecological environment is improved, high yield, stable production and sustained development of rice in saline-alkali adverse situation are promoted. Rice is planted in the sodasaline-alkali land by the method, so the method is simple and easy in operation and convenient to popularize, labor and time are saved, production input cost is low, yield is increased obviously, repair of the fragile ecological environment is facilitated, and income of farmers is increased.

Description

technical field [0001] The invention discloses a rapid desalination and alkali plowing method for paddy fields in soda saline-alkali land, which improves the method for plowing and plowing inland soda saline-alkali paddy fields, and belongs to the technical field of crop cultivation. Background technique [0002] There are generally two forms of traditional farming methods. One is to directly irrigate the field with water and harrow the field after spring plowing. Due to the drought and windy spring, the temperature rises quickly, the air is dry, and the evaporation is large, which can easily lead to soil moisture loss and salt surface accumulation. Aggravation, thus increasing the water consumption of washing alkali in soaking fields; at the same time, due to the lack of dry and wet freezing and thawing in winter and spring in spring, it is not conducive to soil maturation and nutrient conversion, hindering the improvement and restoration of the soil environment in saline-al...
