Fertilization method in astragalus membranaceus seedling cultivation and planting production

Abstract

The invention discloses a fertilization method in astragalus membranaceus seedling cultivation and planting production. The fertilization method comprises the following steps: firstly, uniformly spreading a base fertilizer by using a fertilizer distributor, deeply turning over soil for 50 cm by using a large plough, and horizontally and vertically turning over the soil for two times so that the fertilizer is uniformly distributed in the 0-40 cm portion of the soil; crushing soil blocks by using a power rake, leveling a field, and meanwhile stirring surface soil repeatedly for two times so thatthe fertilizer is uniform; after seeding and before emergence of astragalus membranaceus seedlings, carrying out watering once every five days; after emergence of the seedlings and in the period whenthe heights of the seedlings are less than 10 cm, carrying out watering once every seven days; carrying out watering once every 15 days in the period when the heights of the seedlings are 10-35 cm; carrying out watering once every 25 days in the period when the heights of the seedlings are greater than 35 cm; carrying out thorough watering every time until water reaches a place distant from the ground by 40 cm or above; and spraying a medium trace element foliar fertilizer in three months after seeding. By adopting the fertilization method, the water-oriented property and the fertilizer-oriented property of plant seedlings are sufficiently utilized, the fertilizer and water continuously move downwards in the growth process of astragalus membranaceus through reasonable fertilization operation, the roots of the astragalus membranaceus continuously move downwards, the root length of the astragalus membranaceus seedlings is increased, and branching is relieved.

Description

technical field [0001] The invention relates to a method for using fertilizer in the production process of Chinese medicinal material Astragalus membranaceus. Background technique [0002] Fertilizer plays an extremely important role in agricultural production. It can effectively promote crop growth, increase crop yield, and protect agricultural production. The existing fertilization mode in agriculture is base fertilizer plus late topdressing. Reasonable use of fertilizers can effectively increase production, so good fertilization techniques are extremely important. [0003] The existing fertilization mode in agriculture is base fertilizer plus late topdressing. The traditional fertilization method is to put the base fertilizer (mainly including NPK) and seeds in the seed box at the same time to sow at the same time, saving time and effort, and then add water-soluble fertilizer, including NPK and trace elements. . But such fertilization has many negative effects on the gr...
