Selection of good varieties
Nowadays, bell peppers are not a single variety, it is diverse, but not all varieties of bell peppers are suitable for planting all over the country. So in this case, to get a higher yield of bell peppers, you need to choose the right bell pepper varieties according to the local planting environment. There are currently three varieties on the market, namely, Purple Dragon, Yellow Angel and Orange Angel, which are highly adaptable and have good yields and quality. It can also be considered when planting.
Pay attention to the sowing time
There is a certain difference in the climate between the north and south of China, and the sowing period of bell peppers is also different; there is also the use of different methods of planting what, then it is planted in different times. Scientific planting time, to improve the yield of bell peppers is also very helpful, generally divided into two kinds, the first is early spring planting, the second is late fall planting. Early spring is usually in the end of October seedlings, transplanted in mid to late December, harvested in early March of the following year. In late fall, seedlings are usually sown in mid-August and transplanted in mid- to late-October for harvesting in January of the following year.
Soil selection and consolidation
Sweet peppers are not planted on the soil, but the selection of the right soil and scientific land preparation, which is also conducive to the yield of sweet peppers. The best soil for planting bell peppers is a place with good water supply, good drainage, deep soil layer, strong water and fertilizer retention, and convenient transportation. Generally speaking, the previous crop can not be the same as sweet pepper, and secondly, the planting land is too sticky for sweet pepper planting. Sweet pepper planting land finishing is generally deep plowing, the soil should be a little bit finer, and the soil should be applied with enough fertilizer, such as rotted stable manure, cow dung and so on.
Planting density
Reasonable planting density is also conducive to improving the yield of sweet pepper. To ensure good ventilation and light penetration between bell pepper plants, otherwise bell peppers are very susceptible to anthracnose, ulcers and other diseases, the yield and quality of bell peppers have a great impact. Planting density 60cm, row spacing 50cm.
Scientific water and fertilizer
Scientific water and fertilizer management is the key to improving the yield of bell peppers. The demand for nitrogen, phosphorus and potassium is different for bell peppers in different fertility periods. Fertilization should be divided into three stages. The first stage is growth fertilizer, mainly nitrogen fertilizer, phosphorus fertilizer as a supplement; the second stage is flower fertilizer, mainly phosphorus and potassium fertilizer, nitrogen fertilizer as a supplement; the third stage is a strong fruit fertilizer, mainly potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer. At the same time, attention should also be paid to the use of micro-fertilizers, such as moderate calcium, magnesium, boron and so on. The growth of bell peppers requires sufficient water, especially during the flowering and fruiting period, but it should not be too much, otherwise the phenomenon of rotten fruit will occur.
Growing bell peppers to improve their yield, in addition to the above points, in fact, there are many aspects that can play a role in increasing production. For example, summer pruning, temperature management, light control, pest control, etc., to do a good job of these jobs, the yield of bell peppers can also be guaranteed.
