Problems solved by technology

[0005] ① The emergence rate is low and the water demand is large
[0006] ②Slow growth
[0007] ③Low overwintering rate
[0008] ④ It takes a lot of work and labor to cover the soil before winter
[0009] Although film-covered planting has solved the above-mentioned problems to a certain extent, it still needs further improvement.

Abstract

The invention relates to the field of alfalfa planting, in particular to a Qaidam basin saline-alkali soil alfalfa planting method which comprises the following steps: (a) applying diammonium phosphate and biomass charcoal, turning and preparing land and mulching; (b) sowing saline-alkaline tolerant alfalfa on the film-covered land; (c) field management; the dosage of the diammonium phosphate is 100 kg / hm < 2 >; the dosage of the biomass charcoal is 350 kg / hm < 2 > or 500 kg / hm < 2 >. According to the method, the biomass charcoal and the film are applied to the saline-alkali soil in the Qaidam basin, so that the overwintering problem of the alfalfa can be solved, the amount of applied fertilizer and the number of times of watering are obviously reduced, and in addition, the yield of the alfalfa is obviously increased.

Description

[0001] This application is a divisional application with an application date of November 16, 2017, an application number of 201711134801.7, and the title of the invention "A method for planting alfalfa in saline-alkali land in the Qaidam Basin". technical field [0002] The invention relates to the field of alfalfa planting, in particular to a method for planting alfalfa in saline-alkali land in Qaidam Basin. Background technique [0003] The patent for alfalfa ditching and deep sowing and covering soil previously declared by Gansu Agricultural University is mainly aimed at the planting technology of alfalfa in Gansu and its surrounding low-altitude areas. [0004] In Gansu and its surrounding low-altitude areas, the salinity of the soil is relatively low, the precipitation is relatively high, and the temperature in winter is relatively high. But it is not very effective for planting alfalfa on the saline-alkali land in the high-altitude, arid and cold Qaidam Basin. Mainly ...
