Method for planting figs and improving soil fertility condition in saline-alkali land

Abstract

The invention discloses a method for planting figs and improving soil fertility condition in a saline-alkali land. The method comprises the following steps: application of an organic fertilizer used for improvement of the saline-alkali land for land preparation, propagation, sowing, field management and timely harvesting, wherein the organic fertilizer used for improvement of the saline-alkali land comprises the following components in parts by weight: 42 to 48 parts of animal manure, 12 to 14 parts of plant straw, 10 to 12 parts of tea dust, 8 to 10 parts of bagasse, 6 to 8 parts of seaweed meal, 4 to 8 parts of a pH value regulator, 4 to 6 parts of an adsorbent and 3 to 5 parts of a bulking agent; and the organic fertilizer also comprises 1 to 3 parts by weight of a microbial agent and 0.01 to 0.03 part by weight of rooting powder. The method provided by the invention improves the saline-alkali land by adopting the measures of applying the organic fertilizer used for improvement of the saline-alkali land, planting figs, etc.; the figs have high survival rate and high yield; the improvement effect to the whole saline-alkali land is prominent; and the improvement process is green,environment-friendly and pollution-free. Thus, the method provided by the invention is an application technology which is worthy of large-area popularization.

Description

technical field

[0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a method for planting figs and improving soil and fertilizer conditions in saline-alkali land. Background technique

[0002] At present, there are mainly the following technical measures for the transformation of saline-alkali land:

[0003] 1. Water conservancy improvement, salt washing with fresh water: suitable for well-drained areas with high terrain.

[0004] 2. Biological improvement: improve the micro-ecological environment of saline-alkali land, apply bio-organic fertilizers, supplement organic matter, and increase the number of beneficial microorganisms in the soil, so as to establish a new micro-ecological balance between soil, plants and microorganisms in saline-alkali land, and achieve the goal of biological control.

[0005] 3. Chemical improvement: apply about 15 tons of gypsum per hectare, and apply it once as a base fertilizer. It can also ...
