Experience of field cultivation and management of hot pepper in winter

Management before and after seedling delay: 1. Before slow seedling, mainly to heat preservation and moisturizing, in order to improve the ground temperature, cover with plastic film in time after planting, if there is no plastic film cover, intertillage can be carried out. After slowing down the seedlings to before flowering, generally do not water, only in the drought watering. Before closing the line, it is necessary to cultivate the soil and protect the roots. two。 Fertilization: when the pepper grows to 3 cm, combined with ploughing, 200 grams of rotten farm manure and 10 kilograms of urea are applied per mu. 3. Extra-root topdressing: 100 grams of potassium dihydrogen phosphate can be used to spray 15 kilograms of water, which is beneficial to enhance photosynthesis, promote deep root system and healthy growth of plants, and enhance the disease resistance of plants.

Management of flowering and fruiting period: 1. With 100 grams of potassium dihydrogen phosphate plus 30 grams of urea, 15 kg of water was foliar sprayed at flowering stage, once every 10 days. two。 Timely watering and topdressing should be carried out after each fruit harvest, nitrogen, phosphorus and potassium should be used together, and the principle of "light application of seedling fertilizer, stable application of flower bud fertilizer and heavy application of fruit fertilizer" should be followed to supplement tree nutrition. 3. Do a good job in pruning, branching and soil cultivation: cut off the inner bore branches and old and diseased branches. Leave 2 leaves above the third grade branch for sharpening. At the same time, the soil should be cultivated again to promote new roots and prevent lodging.
