Pollution-free cultivation method for reducing fruit deformity rate of greenhouse strawberry

Abstract

The invention discloses a pollution-free cultivation method for reducing fruit deformity rate of greenhouse strawberry, which comprises the steps of (1) spreading a first cultivation layer in a greenhouse planting zone, covering with a nylon net, covering the top of the nylon net with a second cultivation layer, setting a third cultivation layer above the second cultivation layer, and transplanting strawberry seedlings; (2) controlling moisture, temperature and temperature differences for the strawberry growth process, and irradiating with red light and blue light in different stages; (3) after blueberry blossoms, manually spraying a pollination agent A to flowers in atomized manner every day, loading a pollination agent B into a greenhouse atomizer, carrying out atomizing, and opening airvents in the two sides of the bottom of a greenhouse to arrive at ventilation; and (4) propagating virus-free fruit flies at large scale, releasing the virus-free fruit flies into the greenhouse, performing assisted pollination on strawberry, and recycling the fruit flies after the strawberry pollination stage ends. The method of the invention helps reduce the fruit deformity rate for the strawberry cultivation process, improve strawberry quality and taste, and solve the problems in traditional blueberry pollination.

Description

technical field [0001] The invention belongs to the technical field of strawberry planting, and in particular relates to a pollution-free cultivation method for reducing the deformed strawberry fruit rate in a greenhouse. Background technique [0002] Strawberries are rich in vitamin C, vitamin A and other types of vitamins, and are rich in nutrients such as tannic acid, strawberry amine and pectin. The peristalsis of the intestinal tract can promote the digestion of food in the gastrointestinal tract, improve constipation, and prevent acne and intestinal cancer. It has high nutritional value and is deeply loved by modern people. However, in the process of strawberry cultivation, the harvested strawberries appear to have too thin fruits, which are called cockscomb, flat, uneven fruit surface or multi-headed fruit, random-shaped fruit, green-topped fruit, cracked fruit, stiff fruit and hollow fruit. Deformed strawberry fruit. The main causes of deformed strawberry fruit incl...

Problems solved by technology

However, in the process of strawberry cultivation, the harvested strawberries appear to have too thin fruits, which are called cockscomb, flat, uneven fruit surface or multi-headed fruit, random-shaped fruit, green-topped fruit, cracked fruit, stiff fruit and hollow fruit. Deformed strawberry fruit. The main causes of deformed strawberry fruit include low pollination rate, excessive use of nitrogen fertilizer, soil drought and excessive humidity. Strawberry is a monoecious plant, and its pollination method depends on self-pollination and vector pollination. However, the self-pollination rate is low, and relying on bees for pollination, the activity of bees is limited, and the cost is high, and the mortality rate of bees is high, making it difficult for media pollination to play an effective role; and in the process of strawberry cultivation, organic nutrients, nitrogen Inconsistency in the proportion of ingredients such as , phosphorus, and potassium and the method of fertilization can easily lead to deformity of strawberry fruits
