Method for improving yield of greenhouse cucumbers

Abstract

The invention discloses a method for improving the yield of greenhouse cucumbers. The method includes the steps that ozone is input into a furrow below an earth covering film, suffumigation is carried out on soil through utilization of aluminum phosphide, organic substrate substances are added in the original soil in a greenhouse where the cucumbers are planted in order to improve the structure of the soil, and the temperature difference between inside and outside day and night is controlled and then the growth of the cucumbers is controlled by control over the content of carbon dioxide in the greenhouse, and therefore the yield of the cucumbers can be improved.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method of cucumber in a greenhouse. Background technique [0002] Cucumber is widely cultivated in various parts of China and has become a popular vegetable. Cucumber likes temperature, water and fat, but it is easy to get sick when it is high temperature, and it is easy to die when it is waterlogged, and it is easy to burn the roots if it is too fat. Different stages of the entire growth period have different management requirements. After planting and before harvesting, roots and seedlings should be promoted; from harvesting to full fruit stage, seedlings should be promoted and fruit attacked; after entering the high temperature season, roots and seedlings should be protected to prevent Seedling failure and dead seedlings; as a result, we will continue to strengthen management in the later stage, and various technologies such as increasing production and income are basicall...

Problems solved by technology

Different stages of the entire growth period have different management requirements. After planting and before harvesting, roots and seedlings should be promoted; from harvesting to full fruit stage, seedlings should be promoted and fruit attacked; after entering the high temperature season, roots and seedlings should be protected to prevent Seedling failure and dead seedlings; as a result, we will continue to strengthen management in the later stage, and various technologies such as increasing production and income are basically mature, but there are still some disadvantages in the management of cucumbers in greenhouses, such as greenhouse diseases. Mildew, bacterial angular spot, leaf blight, anthracnose and other soil-borne diseases, once onset, the disease is serious and difficult to control, which will bring great harm to cucumber production

Most of the soil is treated by spraying with medicament mixed with fine soil or irrigated with thicker liquid medicine. The control effect is poor, the cost is high, the duration is short, and many diseases cannot be controlled. The excessive use of pesticides forms a vicious circle, which not only pollutes the soil, but also increases the cost of prevention and control

Methyl bromide fumigation soil disinfection technology has been completely restricted due to its damage to the atmospheric environment

Using lime and straw to treat soil at high temperature in the sun or purely using solar energy for harmless disinfection, the effect is ideal, but both need to last for a long time, and the film used after high temperature treatment is easy to age, resulting in increased control costs
