Sowing method for traditional Chinese medicines in saline and alkaline land

Abstract

The invention relates to the technical field of traditional Chinese medicine planting methods, and in particular relates to a sowing method for traditional Chinese medicines in a saline and alkaline land. The sowing method comprises the steps of (1) applying a base fertilizer, performing deep ploughing and raking, carrying out ridge planting, controlling the ridging space to be 110cm, the bottom width of the ridging surface to be 90cm, the top width to be 70cm and the ridging height to be 25-30cm; (2) digging two rows of sowing ditches in a ridge, wherein the ditch depth is 5-8cm, the average width of the ditches is 5cm, the distance between the center of the bottom of each ditch and the edge of the ridge is 20cm, and the distance between the centers of the bottoms of two ditches is 30cm; (4) performing broadcast sowing or hole sowing in the two ditches on the ridge, and covering the ridge by soil by 1-2cm; and (5) covering the ridge by a black mulching film. By virtue of the technologies such as ridging, ditching in the ridge, coverage by the black film and deep ditch shallow seeding, the difficulties of planting of the traditional Chinese medicines, in particular small traditional Chinese medicine seeds, in the saline and alkaline land are solved; an advanced technical support is supplied to planting of the traditional Chinese medicines in the saline and alkaline land.

Description

technical field [0001] The invention relates to the technical field of planting methods of Chinese medicinal materials, in particular to a method for sowing Chinese medicinal materials in saline-alkali soil. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. In the process of utilization of saline-alkali land, simply put, it can be divided into light saline-alkali land, moderate saline-alkali land and heavy saline-alkali land. Light s...

AI Technical Summary

Problems solved by technology

There are three major problems in the development of Chinese medicinal materials in saline-alkali land. First, it is difficult to sow seeds in saline-alkali land. Due to the influence of saline-alkali, it is very difficult to emerge. Therefore, no matter what type of medicinal materials are planted, the emergence of seedlings is a severe test.

Second, management is difficult. After emergence, dead seedlings often appear, mainly due to the influence of salinity. At the same time, weed control is also an important part that affects the input-output ratio.

Third, most of the seeds of Chinese herbal medicines are small, so it is very difficult to sow, emerge and manage

The seeds of many varieties of Chinese herbal medicines are relatively small. If the moisture content is not good or the soil conditions are not good, it is very difficult to germinate
