Method for planting nostoc flagelliforme in arid-area wasteland

Abstract

The invention relates to a method for planting nostoc flagelliforme in arid-area wasteland. Arid-area water and salt movement rules are fully considered in the nostoc flagelliforme planting process in the method, pressurized microspray irrigation is utilized to supplement water at the appropriate time, ground temperature is adjusted, water and salt are adjusted, growth of the nostoc flagelliforme and surrounding plants is promoted, creation of a low-salt environment required by a seedling stage is facilitated, growth of eremophytes relative to the nostoc flagelliforme is quick, shading protection is provided for growth of nostoc flagelliforme seedlings, and the effects of wind resistance and rainwater washing resistance are achieved for normal growth at a later stage. The method overcomes restraint of the salt-affected soil environment on growth of the nostoc flagelliforme, and technical support is provided for manual plantation of the nostoc flagelliforme and improvement of the arid-area ecological environment.

Description

technical field

[0001] The invention belongs to the field of plant cultivation, and in particular relates to a planting method for sowing lettuce under the condition of sprinkling and irrigation on wasteland in mildly salinized soil in arid areas. Background technique

[0002] Nostocs grows slowly under natural conditions, and provides organic nitrogen and carbon to desert soil through photosynthesis and biological nitrogen fixation, which is of great significance for improving desert soil structure. Nostoc is mainly distributed in arid desert grasslands in Xinjiang, and most of the distribution areas are in remote and poor areas. Only 100 mu of desert grassland with nostocs can harvest 1000g of nostocs, and the average yield per mu is only 10g. Therefore, Fat Choi has been listed as a national second-class key protected plant, and a series of measures have been taken to prohibit digging. However, due to the extremely low yield of Nostocchi, and its high nutritional value,...
