How to do a good job of field management when growing peppers in winter
The winter planting season is about to kick off, and peppers are one of the main varieties grown. To achieve a high yield, field cultivation management must be strengthened. 1. Variety selection: It is advisable to choose varieties with strong plant growth, disease resistance and high yield. 2. Seed treatment and sowing: Generally, seeds are soaked in a chemical solution and raised in a seedbed. For soaking, use 3.5 ml of 0.01% Tianfengsu plus 15 g of 70% Hongri fungicide mixed with 7 kg of water, stir thoroughly, soak the seeds for 12 hours, then remove them for moisture-retaining germination. This can, on the one hand, increase the germination rate, strengthen seedlings and promote rooting, and can also disinfect the seeds and prevent seedling-stage diseases. An appropriate amount of chlorpyrifos can be applied to the seedbed to kill underground pests. The day before sowing, water thoroughly to saturate the soil and apply an appropriate amount of base fertilizer, then evenly broadcast the seeds on the seedbed. 3. Timely transplanting: 1. Land preparation, base fertilizer application, bed making: Peppers have a long growth period and weak roots. To promote the growth of branches and leaves and continuous flowering and fruiting, before transplanting, apply 5000 kg of high-quality farmyard manure and 15 kg of diammonium phosphate per mu in combination with land preparation. Make flat beds 1-1.5 m wide. 2. Transplanting: When the seedlings grow to about 10 cm, under suitable environmental conditions, they can be transplanted to the field. They can be planted at a row spacing of 1 chi x 1 chi, then water thoroughly to settle the roots. 4. Field management: 1. Management before and after seedling establishment: (1) Before seedling establishment, focus on heat and moisture retention. If there is no plastic film mulch, intertillage can be carried out. After seedling establishment and before flowering, generally do not water, and only water lightly during drought. Before the rows close, carry out hilling to protect the roots. Water after hilling, with the amount just enough to moisten the ridge surface. (2) Fertilization: When the first pepper fruit grows to 3 cm, apply fertilizer in combination with intertillage, with 200 g of decomposed dry manure powder and 10 kg of urea per mu. (3) Foliar topdressing: Use 3.5-7 ml of 0.01% Tianfengsu plus 1 liang of monopotassium phosphate mixed with 15 kg of water for foliar spraying, which helps enhance photosynthesis, promote deep root growth, promote robust plant growth, and at the same time enhance the plant's disease resistance. 2. Management during the flowering and fruiting period: (1) Use 3.5-7 ml of 0.01% Tianfeng plus 30 g of urea mixed with 15 kg of water, starting at the flowering stage, spray on the leaves once every 10 days to accelerate plant growth, promote continuous flowering and fruiting, increase the fruit-setting rate, prevent flower and fruit drop, and extend the harvest period. At the same time, improve pepper quality and reduce the occurrence of deformed fruits. (2) Water and topdress fertilizer in a timely manner. Topdressing should be done after each fruit harvest, and nitrogen, phosphorus and potassium should be used in combination to supplement the plant's nutrients. (3) Do a good job of pruning, removing side shoots, removing leaves and hilling: Cut off inner branches and old, diseased and disabled branches. Leave 2 leaves above the third-order branches and pinch off the tips. Remove old and diseased leaves from the lower part to reduce nutrient consumption. At the same time, hill up the soil once more to promote new root growth and prevent lodging. 3. Timely harvesting. When the fruit skin turns green, the fruit is relatively firm and the skin color is glossy, it can be harvested.
