Cultivation of sweet peppers

First, change the habit of breeding and breeding, and select good varieties. Do not weigh, avoid bounty and solanaceous fruit crops, the former crop is wheat, corn, garlic, rape crops as well. Second, nursery transplanting. The 80-day seedling age is appropriate. Bed soil and seed disinfection should be performed before sowing. Seedlings grow to three-leaf and one-minute seedlings, seedlings from 8 cm to 10 cm square, leaving two plants. Seedlings grow to 7 to 8 leaves and colonize at 10 cm to 15 cm height. Third, ditch ridging, film cultivation. From the traditional live-action flat cropping, to the wide-groove and large-line transplanting planting methods. It is convenient for drainage and irrigation, resists diseases, warms and protects the soil, and extends fruit-picking period. In general, the depth of the ditch is 25 cm to 30 cm, and the width of the ditch is 30 cm. 7 days before the planting, the ridge surface is artificially reconstructed, and the ridge surface is covered with a 90 cm plastic film to raise the temperature. Colonization of 4000 points to 5000 points. The seedlings were planted 10 centimeters from the edge of the furrows, and 2 lines per ridge were planted, with the distance between 25 cm and 28 cm. Fourth, watering and fertilizing. In the fall of the first year, 5000 kg of manure was turned over per acre, and ammonium bicarbonate was applied at a rate of 50 kg per acre. Before the planting, 25 kg of ammonium diammonium phosphate per acre was concentrated. After planting, watering topdressing should grasp three key periods: 1. Before flowering and setting fruit, promote rooting and strengthening. When the seedlings survive, when the new roots are sent out, they can be combined with watering per acre according to the soil fertility and plant growth. Topdressing urea 10 kg to 15 kg. 2. After a large number of flowering fruits and fruits have entered the expansion period, critical water should be poured to follow up the critical fertilizer. When the first fruit (Jian Pepper) is about to be harvested, the fruit of the second layer and the third layer begin to expand rapidly, and when the fourth layer of fruit enters the flowering and fruit setting stage, it is the peak period of the green pepper requiring fertilizer, and a heavy dressing is performed. Generally urea topdressing 20 kg to 25 kg per mu. This water and fertilizer catching irrigation is too early, there may be running squatting, causing lush foliage, falling buds. If the topdressing is carried out too late, stalemate may also appear and it is necessary to grasp the “heating”. 3. The management of water and fertilizer in the high-yield period, and grasp the principle of pouring lightly and diligently pouring water and eating less frequently. Generally, about 15 kilograms of urea is applied every acre, which is chased once every half-month to promote the result and increase the yield in the later period. Do not exceed two-thirds of the ditch depth in each watering. Fifth, top dressing. Green peppers enter the fruitful period, to supplement the lack of root sucking fertilizer, keep the leaves dark green, speed up the operation of nutrition to the fruit, can be combined with pest control, spraying concentration of 0.3% potassium dihydrogen phosphate or urea, every 7 days to 10 days Spray once and spray three times in succession.
