Greenhouse cultivation method for pollution-free strawberries

Abstract

The invention discloses a greenhouse cultivation method for pollution-free strawberries and relates to the technical field of cultivation of the pollution-free strawberries. The greenhouse cultivation method mainly includes the steps of 1), variety selection, 2), plant nursery preparation, 3), stock plant selection and field planting, 4), plant nursery management, 5), provisional planting, 6), greenhouse preparation, 7), field planting, 8), greenhouse management, and 9), pest control and prevention. The greenhouse cultivation method for the strawberries is formulated scientifically and reasonably according to growth characteristics of the strawberries, pest control and prevention are performed by adopting efficient, low-toxicity and no-residual chemical pesticides and combining with a physical method, the excellent pollution-free strawberries are produced, yield of products is increased, and quality of the products is improved.

Description

Technical field: [0001] The invention relates to the technical field of pollution-free strawberry cultivation, in particular to a greenhouse cultivation method of pollution-free strawberries. Background technique: [0002] Strawberry, belonging to the Rosaceae Fragaria genus, is a perennial herbaceous plant. Its fruit is bright in color, soft and juicy, and moderately sweet and sour. Berries contain 6-12% sugar, 1-1.5% organic acid, 0.4-0.8% protein, 50-120mg vitamin C per 100g fruit, 10 times higher than apples and grapes, and rich in phosphorus, calcium, iron and minerals such as zinc. At present, compared with advanced strawberry production countries such as the United States, Japan, and Italy, the average yield and quality of strawberries in my country are relatively low, and because growers pursue large and high yields, and the organic matter content of soil in my country is generally low, excessive nitrogen application causes soil pollution. The nitrate content in the...

Problems solved by technology

At present, compared with advanced strawberry production countries such as the United States, Japan, and Italy, the average yield and quality of strawberries in my country are relatively low, and because growers pursue large and high yields, and the organic matter content of soil in my country is generally low, excessive nitrogen application causes soil pollution. The nitrate content in the medium increases, resulting in the poor quality of most of the strawberries sold in the market, and some strawberries have excessive pesticide residues, resulting in unqualified hygiene indicators
