First, pay attention to the "four insects a disease" prevention and control technology Teach farmers to recognize insects, identify diseases, and prevent them on time, and choose pesticides that are effective, low-toxic, toxic residues, and long-lasting pesticides to prevent and control pests and diseases, and to achieve product-free standards. 1. Locust: directly affect the growth of pepper twigs. In the months of June-June and September-October, it is the key to the prevention and control of locusts. In the tender shoot shoots, 2% of the shoots begin to be treated with 30% bags of “70% imirome†and 15 kg of water. Prevention and treatment every 20 days or so, generally Prevention 3-5 times. 2. Zanthoxylum spp., half-lined pupa: In the period of March-June and September-November of each year, the "24% endangered" 10 ml watered 30-45 kg sprayed crowns are used for prevention and treatment, and generally only 2-3 times a year . 3. Pepper heartworms: In late March or before flowering, the use of "10% paddy rice" 15 ml + "70% Antai" 25 g watered 15 kg spraying the crown to prevent Zanthoxylum nitidum, can promote Zanthoxylum growth and increase production by 30%. 4. Prickly sorghum rims: nymphs generally occur in three generations from April to September, the initial stage of the worms use "24% mu-special" 10 ml watered 30-45 kg spray control pests, while effectively preventing the black-pecker locust and red spider pests . 5. Prickly ash rust: It is the main factor that causes the defoliation of prickly ash pepper to reduce the yield, the serious person reduces the production half. In the prevention and control of aphids (early stage of disease occurrence), use "43% Fuli Library" 6ml + "70% imilan" 3g watered 15kg spray canopy, prevent and treat every year from April to May and from September to November. Spray once every 15-20 days, it is generally necessary to control 3-5 times. Second, grasp the pruning time, should sooner rather than later, pruning and harvesting at the same time (i) In June, severe main branch pruning was used as the main method, and pruning was performed on the strong result branch at a distance of 2-10 cm. At the same time, pests and branches, dry branches, overlapping branches, cross branches, dense branches and thin and weak branches were cut off. 2-3 branches were properly retained to promote the growth of new shoots. (B) In July, the main branch was retracted with light weight and trimmed. The results were short at the 15-25 cm branch, and 3-4 branches were appropriately reserved to promote the growth of new branches. (c) Before August 20th, the main branch was gently trimmed and pruned. The results were short at 20-35 cm, and 3-5 branches were appropriately reserved to promote new shoot growth. (D) 8-10 months, according to the growing condition of the pepper, thinning, thinning, leaving branches, left and right branches on each side of the branch, removing the hanging branches and overlapping branches, cross branches, dense branches, thin branches, retain 4 - 5 stout fruiting branches. (E) From 15th to 11th of October, pull branches or branches, wipe buds or shoots, and sparsely cut, regulate the supply and demand of nutrient balance of pepper trees, increase photosynthesis, increase the result area, and increase yield. (6) Topping or tipping in December to control the tip of the pepper tree. (7) Regular inspection of Jiaoyuan from February to May will cut off new growth branches and ensure the vegetative growth of the fruit. Third, the application of four fats is a key (1) Fertilizer (precipitating fertilizer) should also be fertilized 15 days before fruit harvesting. The amount of fertilizer should account for about 50% of the annual fertilization. It is better to apply 40-45% of compound fertilizer with higher nitrogen content (20-25). Dispensing the tree trays or clearing the manure, then cover the soil. (II) The monthly mother-bearing fertilizer (basal fertilizer and rejuvenation fertilizer) is suitable for fertilizing from August to October to apply 40-45% compound fertilizer containing N, P and K balance, which accounts for about 25% of the annual fertilization. (D) to promote flower bud fertilizer in January fertilization to apply low nitrogen high phosphorus high potassium 40-45% compound fertilizer + organic fertilizer, fertilization accounted for about 15% of the annual fertilization. (5) Strong fruit fertilizer (stabilized fruit fertilizer) Fertilizer is applied in the middle and early April. High-phosphorus, high-potassium and micro-fertilizers are mainly used, and the amount of fertilizer accounts for about 10% of the annual fertilization. Guan Jian needs to let farmers know how to determine the content of NPK, and why the proportion of fertilizers is different in the four times. Fourth, minimize the application of herbicides The selection of only secondary herbicides during April-June and September-October is the best control period when weed growth is 4-5 leaves or less than 30 cm. We choose 30-77.7% glyphosate solution or powder for weed control. . Caladium Praetermissum,Caladium Bicolor,Caladium Humboldtii,Caladium Cultivars fanhua nursery , https://www.fanhuanursery.com
