AI Technical Summary

Problems solved by technology

In the 1950s and 1960s, the "dry salt discharge method" was mostly used, but it was gradually eliminated due to low efficiency and unsuitability for large-scale agricultural production.
In the 1970s and 1980s, some dry drainage canals were built. In the case of high irrigation quotas, a whole set of technologies for improving saline-alkali land with water conservancy projects was summed up, that is, the integrated technology of "drainage, irrigation, leveling, and fertilizer". The phenomenon of salinization has only been improved to a certain extent, but the hazard of saline-alkali cannot be effectively eliminated.
Although there are many reports on the preparation of soil remediation agents for the improvement of saline-alkali land, there are no reports on the study of planting Suaeda salsa in saline-alkali land to improve land salinization and the ability to grow edible Suaeda salsa

Embodiment 1

[0022] Embodiment 1: the cultivation method of edible salsa salsa under the conditions of heavy saline soil

[0023] The present invention provides the specific steps of the planting method of edible salsa salsa under the conditions of heavy saline soil as follows:

[0024] (1) Treatment of saline-alkali land: choose severe saline-alkali land, and apply NPK compound fertilizer 225kg / hm as the base 2 , plowing and raking the ground, according to the condition of the plot, ditching is carried out, the distance between the two trenches is 80cm, the depth of the ditch is 15cm, and the dropper belt is arranged in the ditch, and the distance between the dripper of the dropper belt is 30cm.

[0025] (2) Sowing and germination irrigation management: Sowing should be carried out before the first frost or when the low temperature is stable in spring. The seeds are sown at the bottom of the ditch in step (1) saline-alkali land, lightly covered with soil, the thickness of the covering soi...

Abstract

The invention discloses a planting method of edible suaeda salsa on a severe solonchak condition. The method comprises the steps that after nitrogen-phosphorus-potassium mixed fertilizer basal application, ploughing and raking, and ditching and dropper pipe belt arrangement are carried out on severe solonchak, suaeda salsa is sowed before first frost comes or during stable low-temperature period of spring; suaeda salsa is planted in an irrigation and fertilization mode; according to the fertilization mode, 150 kg of urea is applied along with water in a drop irrigation mode for per square hectometer of land and is totally applied 3 times every 15 days, and fertilization is matched with drop irrigation; according to the irrigation mode, 300 m<3> water is irrigated for per square hectometer of land one time every five days when plants grow to 5 cm, irrigation is carried out one time every ten days when the plants grow to 10 cm, and irrigation is carried out one time every fifteen days when the plants grow to 15 cm, wherein the irrigation amount is 300-320 m<3> / hm<2>. Severe solonchak is improved by planting edible suaeda salsa on a large field, and the edible suaeda salsa can be eaten as fresh and tender vegetables.

Description

technical field [0001] The present invention relates to the technical field of saline-alkali land improvement, in particular, to the technical field of the cultivation of edible salsa salsa under severe saline soil conditions. Background technique [0002] Xinjiang is located in the hinterland of the Eurasian continent. Due to the high temperature and arid climate with large evaporation and little precipitation and the topographical characteristics of a closed inland basin, a large area of ​​saline-alkali soil is formed. According to the survey, the area of ​​various saline-alkali soils in Xinjiang reaches 1336.1×104hm 2 , accounting for 36.8% of the national saline-alkali soil area, mainly distributed on the edge of the oasis and inside the oasis, but also sporadically distributed in the edge of the desert, the Gobi desert and mountain water depressions, around the springs. Xinjiang has many kinds of saline-alkali soil and is known as the museum of the world's saline-alkal...
