Technology of planting woads in saline-alkali field

Abstract

The invention relates to a technology of planting woads in a saline-alkali field, namely a high-bed shallow-furrow sparse planting method. According to the detailed process, firstly, the saline-alkali field is modified comprehensively in a water-modifying and soil-fertilizing mode, then a machine is used for plowing a ridge bed, shallow furrows are raked in the middle of the ridge bed, and woad seeds are evenly planted in the shallow furrows; seedling thinning, seedling supplement and intertillage weeding are carried out when the seedling age is 1 month to 2 months, and leaf fertilizer is dressed for one time to two times; and harvest is carried out in sunny days, and folium isatidis and radix isatidis are collected respectively and dried. Compared with a traditional method which has the defects of being large in workload, high in investment, long in time, poor in later-period management and protection, and easily repeating after treatment, the technology of planting the woads in the saline-alkali field has the advantages of being little in investment, easy to operate, time-saving, labor-saving, and not easy to repeat after modification, not only improves the use rate of the saline-alkali field, but also improves the medical quality of the folium isatidis and the radix isatidis, thereby improving ecumenical benefits.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine planting, and in particular relates to a technique for planting medicinal plant Isatis indigo on saline-alkali land. Background technique [0002] Saline-alkali land refers to the land where the salt contained in the soil affects the normal growth of crops, and plants in severe saline-alkali soil areas can hardly survive. Daqing City is one of the areas with serious land salinization in my country. The salinized land is mainly composed of soda alkalized meadow soil, swamp meadow soil and soda salinized meadow alkaline soil. The typical feature is that the surface The amount of evaporation is large, and the salinization of the soil is accompanied by an alkalization process. The main reason for this phenomenon is that the saline-alkali components contained in the soil cannot be metabolized through water-salt movement, resulting in the accumulation of saline-alkali components in the soil. ...

Problems solved by technology

Traditional improvement methods include improving soil and fertilizing, planting saline-alkali-resistant crops, brackish water rinsing, and physical and chemical improvement, etc., but these methods have a large amount of engineering, high investment, long time consumption, poor management and maintenance in the later stage, and prone to occurrence after treatment. Repeated and other shortcomings
