Method for promoting spray-seeding plant lignification

Abstract

The invention provides a method for promoting spray-seeding plant lignification. The method includes: preparing a spray-seeding substrate layer and a seed layer; when seeds germinates, evenly sprayinga diluted activated shell microbial solution to the emergence area; when the seedlings grow true leaves and lateral roots, applying compound fertilizer A to the soil surface; when the seedlings entera fast growth period, applying compound fertilizer B to the soil surface; when the growth speed of the seedlings reduces, applying brown alga extract to the plants and the soil surface; before soil freezing, performing anti-freeze covering on the seedlings. The method has the advantages that different fertilizing methods, fertilizer proportions and fertilizer concentrations are adopted in the different plant growth stages, the self-made base fertilizer, microbial solution and extract are used, the different nutrient requirements of different plant growth stages are satisfied, the required fertilizer proportions in different plant growth stages are regulated, the microbial solution capable of promoting plant lignification is applied, plant lignification is accelerated, plant cold resistance and stress resistance are enhanced, the plants can successfully live through winter, and the next-year survival rate of the plants is guaranteed.

Description

technical field [0001] The invention relates to the fields of plant growth and fertilizers, in particular to a method for promoting lignification of sprayed plants. Background technique [0002] With the rapid development of economy and society, China's infrastructure construction has accelerated, and a large number of exposed slopes have been formed due to the implementation of construction projects such as transportation, water conservancy, mining, and electric power. These exposed slopes not only affect the ecological environment and landscape, but some also have hidden dangers of geological disasters, which affect the safety and stability of the main greening project. Therefore, many places have begun to vigorously carry out slope spraying and greening. Because pure herbaceous greening will make the plant community structure very unstable, it is currently recommended to use herbaceous plants to jointly spray greening, but due to the overdevelopment of herbaceous plants, ...

Problems solved by technology

These exposed slopes not only affect the ecological environment and landscape, but some also have hidden dangers of geological disasters, which affect the safety and stability of the main greening project. Therefore, many places have begun to vigorously carry out slope spraying and greening

Because pure herbaceous greening will make the plant community structure very unstable, it is currently recommended to use herbaceous plants to jointly spray greening, but due to the overdevelopment of herbaceous plants, woody plants will soon have insufficient nutrients, sunlight, water and other resources When the herb plants consume the nutrients in the soil to a certain extent, the slope will decline in a large area, and even return to the state of bare land

On the other hand, due to the uncertainty of the climate, soil conditions, slope gradient and other factors in the construction project area, it will affect the germination, growth and lignification process of woody plants in the spraying matrix, resulting in woody plant seedlings in winter. Because there is not enough time for lignification before the arrival, the seedlings are seriously affected by the poor ability to resist cold and frost. This kind of seedlings often have a very low survival rate in the second spring due to frost damage.
