The latest key points of water and fertilizer management of sweet pepper

Sweet pepper is a very popular plant of the genus capsicum, which has a large planting area in China. When planting sweet pepper, if you want to improve the yield and quality of sweet pepper, then water and fertilizer management is very important. Only by doing a good job of water and fertilizer management can we ensure that the nutrition and moisture needed for the growth of sweet pepper can be met. So how to manage water and fertilizer when planting sweet pepper? Today, the editor brings you the key points of sweet pepper water and fertilizer management. Let's take a look at it.

I. watering management

1. Planting water

After the sweet pepper is planted, we have to pour planting water for once. Watering can be carried out on the same day or the next day, and the amount of water should be kept at about half the depth of the ditch. We must be careful not to let the water overflow to the border surface. After watering the planting water, we must begin to control the amount of water. Until sweet pepper door pepper blooming about 3 days before the beginning of watering, this watering is called flowering water. Wait until the water penetrated into the soil, and then combined with the soil loosening work to carry out deep hoe, and then cultivate the soil to the roots of the seedlings to avoid the temperature drop and affect the growth of sweet pepper.

2. Promoting flowering water

About a week after we call the flower water, we will water it again, and this time we should apply the right amount of urea in conjunction with fertilization. Then, after about 5 days, the fourth watering work is carried out, and this time the watering should be combined with the application of appropriate amount of compound fertilizer. After the sweet pepper enters the fruit expansion period, we must pay attention to keep the soil moist, watering about once a week, watering should be based on the principle of a small number of times. Then pay attention to control the watering time, should be carried out in the morning and evening, especially before the hot weather, be sure to water in time before the temperature rises in the morning. However, it is necessary to control the amount of water, and if it produces stagnant water, it should be drained in time.

II. Fertilization management

1. Topdressing

After the sweet pepper seedlings were successfully slowed down, the first topdressing work began. For the seedlings, the stable high nitrogen fertilizer should be selected, and about 30kg should be applied per mu. Then the second topdressing work was started at the budding stage of the plant, keeping the same ratio of nitrogen, phosphorus and potassium, mainly available fertilizer. After entering the fruiting period of sweet pepper, before the chair is harvested, each watering should be combined with topdressing work. Fertilizer can be used alternately with compound fertilizer with high nitrogen and potassium to meet the English needs of sweet pepper growth.

2. Medium and trace elements

In the whole growth period of sweet pepper, we should pay attention to supplement calcium. If calcium is insufficient, sweet pepper is prone to navel rot. High-quality liquid calcium fertilizer can be sprayed on the leaves of sweet pepper to supplement calcium. Then we should also pay attention to the supplement of magnesium. In the early stage of planting, sweet pepper absorbed little magnesium, but began to increase during the harvest period. At this time, if magnesium is insufficient, the leaf veins are easy to yellowing, which is very disadvantageous to the growth and fruit of the plant, and can also be supplemented by foliar fertilizer. Finally, we should also pay attention to boron to avoid the lack of boron in the plant.
