Pollution-free cultivation method for reducing malformed fruit rate of strawberries in greenhouse

Abstract

The invention discloses a pollution-free cultivation method for reducing the malformed fruit rate of strawberries in a greenhouse. The pollution-free cultivation method comprises the following steps that (1), a first cultivation layer is laid in a greenhouse planting area, the first cultivation layer is covered with a nylon net, a second cultivation layer is laid at the upper part of the nylon net, the upper layer is used as a third cultivation layer, and strawberry seedlings are transplanted for planting; (2), moisture, temperature and temperature difference in the strawberry growth process are controlled, and irradiating is carried out by using red light and blue light in different periods; (3), after the strawberries bloom, a pollination agent A is manually atomized and sprayed to flowers every day, then a pollination agent B is loaded into a greenhouse atomizer for atomization treatment, and ventilation openings in two sides of the bottom of the greenhouse are simultaneously opened for ventilation; and (4), mass propagation is carried out on detoxified fruit flies, the detoxified fruit flies are put into the greenhouse, auxiliary pollination is carried out on the strawberries, and the fruit flies are recovered after the pollination period of the strawberries is ended. According to the pollution-free cultivation method for reducing the malformed fruit rate of the strawberries in the greenhouse, the malformed fruit rate in the strawberry cultivation process is reduced, the quality and taste of the strawberries are improved, and the problem of traditional strawberry pollination is solved.

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
