Summer and autumn season is the season when fruits and vegetables grow more vigorously. However, improper management of farmer friends can easily cause premature failure of such vegetables and reduce production. Therefore, effective measures should be taken early to prevent premature aging. 1, timely pruning, removal of old leaves. After the first batch of peppers are picked, 8 branches growing on the four large branches growing near the base are cut off. Cucumbers should be picked up in 25 leaves to promote the formation of melons, otherwise it is easy to cause obstruction of nutrient transportation. Tomato picking time should be after the fourth panicle flower set and leave two leaves on the ear fruit, so as to avoid premature root failure and leaf curling under the plant, should not be picked in the fourth inflorescence just to blossom. 2, timely fertilizer. Provide sufficient nutrients for plant growth and development. The best time for topdressing after harvesting the fruit can generally be combined with irrigation to catch decomposed human excreta or nitrogen and phosphate fertilizers 1 or 2 times. Cucumber 10 kg per 667 square meters topdressing DAP, eggplant 10 kg per 667 square meters topdressing urea, pepper chase fertilizer material should be more appropriate, per 667 square meters can be applied about 12 kg of ammonium phosphate, but need to Fertilizers are soluble in water and are not suitable for planing. 3, disease prevention and pest control. Fruit and vegetable vegetables should pay attention to the early control of aphids in time, generally available 20% erythrhinyl emulsion 800 ~ 1000 times sprayed leaves. Cucumber powdery mildew can be used 50% thiophanate 800 ~ 1000 times spray control, cucumber downy mildew can be used 40% 300 aluminum and 300 times 400 aluminum spray control. Control of tomato botrytis can be sprayed with 75% chlorothalonil wettable powder 600 to 800 times. Prevention of eggplant blight, in the early stages of its onset, 75% chlorothalonil 700 times liquid spray, spray once every 7 to 10 days, spray a total of 3 to 4 times, spray evenly sprayed on the leaves and fruits, so In order to achieve better control effect.
