Breeding method for strawberry seedlings in northwest cold and arid regions

Abstract

The invention discloses a breeding method for strawberry seedlings in northwest cold and arid regions. The breeding method comprises the following steps that cruciferous waste vegetable fragment tissues are laid on the earth surface to disinfect soil, an organic fertilizer leavening agent is sprayed on the surface of waste vegetable residues, enough water is poured to the soil after subsurface tillage for film mulching fermentation, and ploughing, ventilation and moisture dissipation are carried out after fermentation and decomposition; fertilizing and ridging are carried out, and drip irrigation tapes are laid; field planting is carried out after high-quality seedlings are selected and subjected to root soaking treatment, and rooting water is poured to the seedlings immediately and thoroughly after field planting; and a small arched shed is built, the seedlings are covered with films, the films are broken to expose the seedlings, and conventional field management is carried out. According to the breeding method for the strawberry seedlings in the northwest cold and arid regions, the waste vegetable fragments are adopted for soil disinfection, and after waste vegetables are rottedand decomposed, the physicochemical properties such as soil water-holding capacity, fertility, organic matter content and permeability can be improved, so that the application amount of chemical pesticides is reduced; meanwhile, the disinfection raw materials are agricultural waste materials, so that the production cost is low, agricultural waste recycling is achieved, and environmental pollutionis reduced; and after field planting, the small arched shed is immediately built for heat preservation, moisture preservation, water saving and drought resisting, so that seedling recovering time is shortened, the seedling survival rate is increased, the strawberry yield is remarkably increased, and the breeding method is suitable for popularization and application.

Description

Technical field[0001]The invention belongs to the technical field of seedling breeding, and particularly relates to a method for breeding strawberry seedlings in the cold and arid regions of northwestern China.Background technique[0002]Strawberry belongs to the Rosaceae plant. It is favored by consumers because of its high nutritional value, tender and juicy, and strong fragrance. Strawberry has a short planting cycle, early results and high economic benefits. It has become the fastest growing emerging industry in facility gardening.[0003]When planting strawberries, suitable temperature and humidity are required, and sufficient soil moisture is required, otherwise its yield and fruit quality will be greatly affected. When planting strawberries in arid and semi-arid regions, the common problems are low seedling breeding rate, poor quality of seedlings, and serious obstacles to continuous cropping.

Problems solved by technology

When planting strawberries in arid and semi-arid areas, the common problems are low seedling breeding rate, poor seedling quality, and serious obstacles to continuous cropping. This is also one of the main reasons for the low quality of strawberry seedlings in the cold and arid regions of Northwest China.

At present, the main measure to improve the breeding rate in strawberry seedling breeding is to use a large amount of ground watering combined with multiple leaf sprays to maintain sufficient soil and air humidity, but there are three main problems in this method, the first is time-consuming and labor-intensive. The amount of water is uneven, and the germs spread quickly with the running water. The second is that the water demand is large, which wastes resources. The third is that a large amount of water can easily cause soil compaction, and the soil temperature is too low to affect the growth of stolons.

However, to solve the problem of continuous cropping obstacles in traditional cultivation, chemical pesticides are usually used to treat the soil, which can easily cause pesticide residues, crop damage, drug resistance, and pollute the environment
