Method for planting cucumbers in greenhouses

Abstract

The invention discloses a method for planting cucumbers in greenhouses. The method includes fixedly planting 4000-4500 cucumber seeds in each mu of greenhouse sheds, timely watering the cucumber seeds, applying 15-20 kilograms urea, 10 kilograms of potassium sulfate and 15 kilograms of diammonium phosphate to cucumber plants in each mu after root cucumbers are expanded, applying fertilizers once whenever the cucumbers are harvested twice in the future, and applying thoroughly decomposed dilute manure along with water by 2-3 times in middle and later periods; keeping the air humidity suitable for growth and development of the cucumbers in the range from 60% to 80%, and instantly ventilating the greenhouse sheds and exhausting moisture in the greenhouse sheds when the humidity of the insides of the tents exceeds 85%; ventilating the greenhouse sheds for 1-2 hours so as to reduce the humidity of the greenhouse sheds at night when the air temperature ranges from 10 DEG C to 15 DEG C at dusk, starting to tie vines when the lengths of the cucumber vines reach 30 centimeters, and moistening flowers by 100-multiplied liquid of fruit retention hormones or spraying the 100-multiplied liquid to the flowers after the cucumbers are born. 1000 kilograms of the thoroughly decomposed dilute manure are applied to the cucumber plants in each mu of the greenhouse shed in each procedure. By the aid of the 100-multiplied liquid of the fruit retention hormones, the cucumber sit rate is high, the cucumbers can be retained, and the small cucumbers can be promoted to be quickly expanded. The method has the advantage that cucumber and vegetable planting can be quickly developed in a large-scale, low-cost, high-benefit and pollution-free manner by the aid of the method.

Description

technical field [0001] The invention belongs to the technical field of cucumber vegetable planting, in particular to a method for growing cucumbers in a greenhouse. Background technique [0002] China is the largest producer and consumer of cucumber vegetables and melons in the world. According to statistics, in 2008, China's harvested area of ​​cucumber vegetables and melons was 24.08 million hectares, with a total output of 457.73 million tons, accounting for 44.5% and 50% of the world; ranking first in the world, 2.9 and 4.8 higher than the second-ranked India times. Cucumber is rich in cellulose, various vitamins and mineral elements. It is the main vegetable that our people like to eat. Cucumber has high yield and wide adaptability, and can be cultivated in both north and south of my country. In particular, the maturity of grafting technology and cultivation technology in protected areas enables the people to eat fresh cucumbers all year round. [0003] The develo...

AI Technical Summary

Problems solved by technology

From a national perspective, the total production of cucumber vegetables is almost saturated, but this is only the saturation of low-level varieties and quantities, while the supply of green cucumber vegetables and organic cucumber vegetables is far from meeting the growing market demand. The volume is constantly increasing, the market capacity is large, and the development space is broad
