Winter pepper planting needs to strengthen field management

Now the winter planting curtain is about to be lifted. Pepper is one of the main varieties. In order to achieve high yield, it is necessary to strengthen the field cultivation management.

1. Variety selection: varieties with strong plant growth, disease resistance and high yield should be selected.

Second, seed treatment and sowing: generally use medicament soaking seeds, using seedbed to raise seedlings. Soak the seeds with 0.01% Tianfengsu 3.5 ml plus 70% Hongri fungicide 15 grams with 7 kg of water, stir the seeds thoroughly and soak the seeds for 12 hours, remove them for moisturizing and sprouting. On the one hand, it can improve the germination rate, strengthen seedlings and promote roots, but also disinfect seeds and prevent seedling diseases. The seedling bed can be used with an appropriate amount of chlorpyrifos to kill underground pests. The day before sowing, the bottom water should be irrigated and the appropriate amount of base fertilizer should be applied, and then the seeds should be spread evenly on the seedbed.

Timely planting: 1. Soil preparation, application of basic fertilizer and planting: pepper has a long growth period and weak root system. In order to promote branch and leaf growth and continuous flowering and fruiting, 5000 kg of high-quality farm manure and 15 kg of diammonium were applied per mu before planting. The border is made into a flat bed 1-1.5 meters wide. 2. Transplanting: when the seedling grows to about 10 cm, it can be moved to the field under suitable conditions, which can be planted according to the row spacing of 1 foot × 1 foot, and then irrigated with enough water for fixed roots.

IV. Field management:

1. Management before and after seedling retardation:

The main results are as follows: (1) before slow seedling, it is mainly to keep warm and moisturizing, if there is no plastic film mulching, it can be ploughed in the middle. After slowing down the seedlings to before flowering, generally do not water, only in the drought watering. Before sealing ridges, it is necessary to cultivate the soil and protect the roots. Watering after soil cultivation, it is appropriate to wet the ridge and platform with water.

(2) fertilization: when the door pepper grows to 3 cm, combined with ploughing, 200 grams of rotten dung dry powder and 10 kilograms of urea are applied per mu.

(3) extra-root topdressing: 0.01% Tianfengsu 3.5-7 ml plus potassium dihydrogen phosphate 1 pair of water 15 kg for foliar spraying, which is beneficial to enhance photosynthesis, promote deep root rooting, promote the healthy growth of plants, and enhance the disease resistance of plants.

2. Management of flowering and fruiting period:

(1) 0.01% Tianfeng 3.5-7 ml plus 30 grams of urea and 15 kg of water were foliar sprayed every 10 days from the beginning of flowering to speed up plant growth, promote continuous flowering and fruiting, improve fruit setting rate, prevent flowers and fruits from falling, and prolong the harvest period. At the same time, improve the quality of pepper and reduce the occurrence of deformed fruit.

(2) timely watering and topdressing should be carried out after each fruit harvest, and nitrogen, phosphorus and potassium should be used together to supplement the nutrition of the tree.

(3) do a good job in pruning, branching, picking off and cultivating soil: cut off the inner bore branches and old and diseased branches. Leave 2 leaves above the third grade branch for sharpening. Remove the old and diseased leaves in the lower part to reduce nutrient consumption. At the same time, the soil should be cultivated again to promote new roots and prevent lodging.

3. Timely harvest; when the pericarp turns green, the fruit is hard and the skin color is bright, it can be harvested.
