Temperature: open the grass and heat up at about 9: 00 in the morning, and cover the grass at about 5: 00 in the afternoon to keep warm. The heating rate in the shed should not be too fast. At the beginning, the grass will be exposed every other day, and after 7 days, it will all be uncovered.

Humidity: the relative humidity in the shed is 70-80% from heating to pre-flowering, 50-60% during flowering, 40-60% after falling flower to harvest, and spraying water to increase humidity below 40%.

Watering: under normal circumstances, water can be watered 3-4 times from heating up to harvest. The first sprouting water, combined watering, urea 200-250 grams per plant; after the second flower drop, combined watering, 150 grams of urea plus 150 grams of diammonium phosphate per plant, or 250 grams of ternary compound fertilizer. The third time in the fruit expansion period, in addition to combined watering nitrogen, phosphate fertilizer, each plant should add 100 grams of potassium sulfate. For the fourth time, about 15 days before harvest, if watering is needed, available potassium should be the main topdressing.

Foliar fertilizer spraying: after falling flowers, quick-acting fertilizer should be sprayed every 15-20 days. 0.3% urea can be sprayed in the early stage, 0.3% potassium dihydrogen phosphate can be sprayed in the later stage, or both can be sprayed, or other foliar fertilizers can also be sprayed.
