There are four ways to increase the yield of cucumber in greenhouse.

Foliar fertilizer spraying

Spraying 0.3% urea solution at the seedling stage can promote the early development of seedlings. It can also be sprayed with 0.5% ferrous sulfate solution to promote seedling setting and make the leaf color dark green. Spraying 0.2% boric acid solution in 7 leaves can protect flowers and fruits; in a large number of melons, spraying 0.3% potassium dihydrogen phosphate solution and 0.5% urea aqueous solution can increase melon yield.

Artificial assisted pollination

The artificial pollination of cucumber after flowering, aiming the collected male stamens at the stigma of pistil, and applying it gently can restrain the phenomenon of cucumber shedding and meloning, increase the fruit setting rate and increase the yield of cucumber.

Artificial castration

Go to the male once every five days in the peak period of melon, leaving 5% and 10% of the male flowers. At the beginning of the melon, the distance between male and female can be longer, once in 6-7 days. Castration of cucumber can reduce nutrient consumption, promote plant development and increase yield.

Pick the heart

The operation of picking the heart after sitting on the weak side vine can increase the population of sitting melon and increase the yield. Zhang Yu
