Recently, when the reporter interviewed Wuquan Town in the Yangling Demonstration Area in Shaanxi Province, he discovered that the vegetable shed of Yao Xiaohong, a vegetable farmer, was in full swing. He asked if the neighboring vegetable growers had observed and studied in Yao Xiaohong's vegetable shed. Yao Xiaohong is a cucumber planting expert recognized by the surrounding villagers. After many years of continuous exploration, Yao Xiaohong's greenhouse cucumber planting experience has been very effective.
Light smoke shed When the cucumber seedlings grow to 1-4 true leaves, light smoke is added to the greenhouse, keeping the seal for 2-3 days and nights, increasing cucumber female flowers and increasing cucumber yield. This is because the smoke contains carbon monoxide, which inhibits the oxidation process in the seedlings, allowing the melon to form numerous female flowers. At the same time, smoked can also kill cucumber spider mites. Changing the smoke to gas can also receive better results.
Artificial pollination cucumbers are unisexual flowers, which are divided into male and female. In the field, they are pollinated by insects. Because there is no insect in Wending as a medium, it will cause poor pollination affect melons. If in the appropriate period after the flowering of the protected cucumber, the male stamens of the collected flowers are applied several times to the stigmas of the female flowers, artificial pollination can be achieved, reducing the loss of female flowers, increasing the rate of sitting cucumbers, and increasing the size and length of the cucumbers. , delicious color and delicious.
Red light irradiation using red light bulbs every night for 2-3 hours, can significantly increase the yield of cucumber. If flickered pulsed light is used, the yield can be higher than continuous light.
The addition of gas fertilizers puts several barrels of fertilizer in the greenhouse, and uses the fermentation method to increase the concentration of carbon dioxide in the room. It is also possible to produce carbon dioxide by burning firewood and burning stoves in winter. Especially in the greenhouse where heating is used, it is more important to add carbon dioxide gas fertilizer.
Foliar spray fertilizer spraying 1% urea solution at seedling stage, can promote seedling early-onset, can also spray 0.5% ferrous sulfate aqueous solution, promote seedling strong, strong green leaf color; in 7 leaves, spraying 0.2% boric acid solution To prevent the falling of Guagua; in a large number of fruiting melons, spray 0.3% potassium dihydrogen phosphate and 1% urea mixture to make up fat, promote melon production.
The traditional ground gully irrigation of micro-water irrigation, the greenhouse temperature and the ground temperature are obviously reduced, and the humidity is increased, which is not conducive to the growth of cucumber, and the pests and diseases are serious. Greenhouse cucumber with micro-irrigation is used, and groundwater irrigation is conducted in a suitable period. The drip pipe is placed in double high ridges covering the mulching film, which does not affect the ground temperature, but also saves water, reduces pests and diseases, and improves the yield and quality of cucumber.
