Method for treating greenhouse strawberry continuous cropping field soil

Abstract

The invention belongs to the planting technology of crops and relates to a method for treating the soil of a continuous cropping field of greenhouse strawberry. The method includes the following steps: a. plants are pulled out as soon as the harvest of the greenhouse strawberry is finished during May to July every year and ground surface covering materials like black plastic film, etc. are removed; b. green bran, the glume of which is removed, is scattered, the amount is 500-750 kg per mu, and the rice bran is evenly mixed into the soil by adopting mechanical and manual method for intertillage weeding; c. surrounding ditches around the greenhouse and the interior of the greenhouse are fully irrigated with water, and the soil in the greenhouse becomes saturated by absorbing water; d. the field surface in the greenhouse is covered with undamaged plastic film, the soil around the plastic film is firmly pressed to prevent air from entering until August to September when strawberry is to be planted. The method can eliminate the obstacle of continuous cropping of strawberry, causes no pollution to the environment, and provides better organic fertilizer for the growth of strawberry, thus having good comprehensive economic benefit.

Description

technical field [0001] The invention belongs to crop planting technology, and relates to a soil treatment method for strawberry continuous cropping fields in greenhouses. Background technique [0002] Strawberries have high nutritional value, come on the market early, have a short production cycle, and have quick results. They are regarded as winter and spring fruit treasures and are high-efficiency economic crops for "green winter". However, with the expansion of production scale, the planting area increases, and the number of heavy cropping land increases, the harm of strawberry root diseases increases year by year, causing huge economic losses to farmers and becoming one of the main obstacles to the development of strawberry industry. Strawberry continuous cropping disease is a compound root disease caused by soil-borne pathogenic fungi, nematodes and other environmental factors. The main symptoms are that the heart leaves of seedlings turn yellow-green or yellow curly, n...

Problems solved by technology

Fertilization with traditional chemical fertilizers is difficult to achieve a balanced supply of nutrients. Nitrogen is often too much. Although it can promote fruit development for a while, it directly affects the differentiation of the next batch of flower buds.

However, if the organic fertilizer that has not been fully decomposed and fermented is directly applied to the strawberry ridge, the phenomenon of root burning will be serious, and the slow seedling period after planting will be long, often resulting in lack of plants and broken ridges.
