After entering the months of July and August, there has been a certain amount of production of open-chili peppers, but in order to achieve high yields, the management measures in the later period must keep pace. There are two major aspects of this issue of pepper management:
I. High-yield measures
1. Water and Fertilizer Management After entering the months of July and August, the roots begin to age, but this period is a critical period for peppers, so a top-dressing fertilizer is needed to strengthen the management of water and fertilizer in the later period. Per acre with water topdressing urea 15 kg + potassium sulfate and other 2-3 kg, to maintain the normal growth of medlar, if serious fruit drop can also add 150 grams of boron and zinc fertilizer.
2. Anti-falling peppers are most prone to falling, falling, and falling leaves in the hot season. Mainly related to temperature and humidity, light, trace elements and diseases. Therefore, in the fruit setting period of the pepper, spraying the enemy stable 3000 times liquid, 15-20 days or so, continuous spraying 2 times, can prevent the pepper drop, increase the fruit setting rate.
3. Prevention of premature senescence in premature defoliation of pepper is the most critical factor affecting yield. Premature senescence is the most direct manifestation of root ageing. Therefore, foliar spray fertilizer is applied to increase fertilizer and top dressing is applied to prevent premature aging. The purpose of “guarantee many fruits and red peppers without falling leavesâ€. The specific measure is that from the middle of August onwards, the foliar spray of potassium dihydrogen phosphate 600 times, 10 to 15 days once, and even spray 2-3 times.
4. Guaranteeing hot peppers Due to the hot weather in July and August, together with the lack of calcium, it is very easy to cause umbilical rot in peppers, which is to begin browning in the middle and upper parts of the peppers and dry and black afterwards. The people are commonly called “skinsâ€. Severely affect the quality of pepper when severe. Prevention and treatment can be sprayed with 1500 times Riparel Calcium, 7 days once, and even spray 2 times, while watering in time.
Second, pest and disease prevention
Pests and diseases are a major obstacle to the high yield of pepper. The main pests and diseases of pepper are: blight, bacterial wilt, and root rot.
1. The disease can be used to kill poisonous maggots, thiazolycin Mn-Zn, Garrinon, Phytophthora net and so on.
2. Bacterial wilt can be used in the initial stage of disease, 72% of agricultural streptomycin sulfate 0.25 sputum, bacterial spirit 0.25 sputum and other irrigation roots, 100-150 ml per irrigating solution, once every 7-10 days, continuous irrigation 2 to 3 times.
3. Root rot available in the early stage of disease can be used 3% Kwong Ling water agent 1000 times plus 70% pure Ketuo wettable powder 1000 times or 3% Kwong Ling water agent 1000 times plus 50% carbendazim can Wet powder 1000 times liquid irrigation control, each strain of irrigating solution 100 ~ 150 ml, every 7 to 10 days irrigation once, with irrigation 2 to 3 times.
4. The main insect pests that injure peppers are locusts, small earthworms, tobacco budworms, and tea plant glycosides. They can be treated with 2.5% deltamethrin, 10% once-a-day net, 1% insecticidal, and 73% ketal.
