Greenhouse cucumber production increase new technology
Light smoke shed When the cucumber seedlings grow to 1 to 4 true leaves, light smoke is poured into the greenhouse, sealed for 2 to 3 days and nights, and the cucumber female flowers can be increased to increase the 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, smoking also kills red spiders. Artificial pollination cucumber is a single flower, male and female, in the field, mainly by insect pollination. Because there are no insects in the greenhouse as a medium, it will cause poor pollination and affect melons. If artificial pollination is performed after the cucumbers in the protected area are blossomed, the female flowers can be reduced and the rate of sitting can be increased. At the same time, the melons are large, long, fresh and delicious. Red light irradiation using red light every night for 2 to 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. Burning firewood can also be performed on a regular basis. The method of producing a stove in winter produces carbon dioxide. 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 to promote seedling robust, leaf color dark green; in 7 leaves, spray 0.2% boric acid solution , Guagua anti-drop; in a large number of fruiting melon, spray 0.3% of potassium dihydrogen phosphate and 1% urea mixture to supplement fertilizer, promote melon production. The traditional ground irrigation of gully irrigation in micro-water irrigation, greenhouse temperature, ground temperature is significantly reduced, the temperature is increased, is not conducive to the growth of cucumber, and serious diseases and insect pests; the use of micro-irrigation, irrigation water appropriate period of small irrigation, and the drip pipe on the cover film double In the high ridge, it does not affect the temperature, but also save water, reduce pests and diseases, and increase the yield and quality of cucumber.
