Watering
1. Water control is needed after emergence. If the humidity in the bed is too high, the plants can be dusted and fine soil can be adjusted. Watering depends on the soil, seeing dry and wet. The bed soil should not be whitish or watered. The watering should be carried out at noon on a sunny day. After pouring, the water should be ventilated and drained.
2. After the 4-leaf stage of the seedlings, if the seedling bed is short of water, it should be watered in time, and watering should be carried out between 10 and 13 o'clock.
3. 7-10 days before planting, the seedlings are cut off by water, and the seedling bed is watered once a day before planting. Before transplanting peppers, you must pay attention to the selection of herbicides, and the residue period is too long to choose. When transplanting, pepper seedlings should be at a certain distance from the bottom fertilizer applied to the strips to prevent burning and dead seedlings of peppers.
top dressing
1. Foliar top dressing is generally carried out at the seedling stage of pepper. Starting from the unfolding period of the fourth true leaf, a mixture of 0.4% potassium dihydrogen phosphate and 0.6% urea water is applied once every 7 to 10 days. When the leaves are yellow and the bottom fertilizer is insufficient, it can be applied with urea in the 6, 8, and 12 leaf stages. 150 to 200 grams per bed, pouring a little water after application.
2. Spray 0.2% urea + potassium dihydrogen phosphate twice a week before transplanting, and spray a 75% chlorothalonil 800 times solution 3 days before transplanting to control the spread of the bacteria.
Insect control
Check whether there are aphids and planthoppers in the wheat field around the seedbed, and spray imbiprofen and other systemic and contact-type insecticides on the bed in time to prevent the spread of viral diseases.
