Embodiment 1

[0054] 1. Land selection

[0055] Choose sandy loam land with flat terrain, good drainage and irrigation, strong water and fertility retention, and potatoes as the previous crop as the seedling nursery.

[0056] 2. Land preparation

[0057] 30 days before the seedlings were raised, the soil was prepared, and the submerged and rotary tillage machine was used to work 35-45 cm to level the land. The operation requirements were: deep plowing, leveling the land, loosening the land, and timely removal of weeds, grass roots, and previous crops. and weeds, straws, stones, branches, and plastic film; among them, after the soil is loosened, the diameter of the soil particles is less than 2cm.

[0058] 3. Base fertilizer application

[0059] When applying basal fertilizer, fully mix the soil and basal fertilizer until the mixture is uniform, and it is advisable to apply enough base fertilizer at one time;

[0060] Among them, the base fertilizer is 150kg / mu of biological enzyme and ac...

Abstract

The invention discloses a film mulching and sand pressing seedling raising method for astragalus membranaceus. The seedling raising method comprises the following steps that (1) astragalus membranaceus seeds are pretreated with a microbial agent to obtain pretreated astragalus membranaceus seeds; and (2) after base fertilizer is applied, the pretreated astragalus membranaceus seeds are placed in mulching film holes, covered with fine soil for pressing, and then covered with washed river sand for pressing. According to the film mulching and sand pressing seedling raising method for the astragalus membranaceus, the seedling emergence rate is high, and the yield is high; the seed emergence time is short; the seedlings are high in resistance and low in morbidity; soil moisture conservation and weed suppression are achieved, the air permeability is high, and hardening can be effectively prevented; the seedling quality is good; meanwhile, the labor intensity is reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a method for raising seedlings of Astragalus membranaceus covered with film and pressed with sand. Background technique [0002] The medicinal use of Astragalus has a history of more than 2,000 years. It has the functions of enhancing the body's immune function, protecting the liver, diuresis, anti-aging, anti-stress, lowering blood pressure and a wide range of antibacterial effects. [0003] Northwest China is the main production area of ​​Astragalus membranaceus. At present, most of the seedlings used in the production of traditional Chinese medicinal materials in Northwest China are self-propagation and self-cultivation by farmers. There is no uniform standard for seedling breeding technology, and scientific and technological means are rarely used to raise seedlings. In addition, there are still low spring temperatures, drought and little rain in Northwest China, which leads to irregular growth of Astragalus membranaceus see...
