Matters needing attention in grafting of chili

There are still a lot of pepper planted in our country, and there are many varieties of pepper in our country. No matter what kind of variety it is, it is more popular. When planting pepper, in order to improve the yield and growth ability of pepper, most of the seedling methods are based on grafting. When grafting chili peppers, there are many things we need to pay attention to. So what are the points for attention in pepper grafting? The following editor will give you a brief introduction, let's have a look!

1. Scion selection of rootstock

When grafting chili peppers, the first thing we should pay attention to is to select rootstocks and scions. Rootstocks should have strong resistance to soil-borne diseases and pay attention to understand the affinity of pepper scion. To avoid diseases such as Fusarium wilt in the fruiting period due to poor affinity. Then we should pay attention to selecting pepper cuttings according to local market demand, consumption habits and planting stubble. If overwintering cultivation is needed, cold-tolerant, shade-tolerant and moisture-tolerant pepper varieties should be used. If it is planted in early spring or delayed in autumn, then it should be mainly early-maturing varieties.

2. Pay attention to sowing

The grafting method of pepper is generally split grafting, and there is a certain interval between the sowing time of pepper rootstock and scion. Should pay attention to the division of the two kinds of cotton bolls, generally should be in the rootstock two cotyledons fully unfolded before sowing scions. Before sowing, the seeds of rootstocks and scions should be scalded with hot water of about 60 degrees, and pay attention to stirring when blanching seeds. Soak seeds for 12 trifles when the water temperature drops to about 30 degrees. Then take it out and put it in a 35-degree environment to promote germination and wash the seeds with warm water once a day. When sprouting, you should be careful not to touch oil stains, not to put them in heavy metal utensils, and not to wrap seeds with plastic film.

3. Pay attention to the seedbed

The seedbed for growing chili peppers should first ensure that no eggplant fruit vegetables have been planted within three years, and then ensure normal drainage and irrigation and convenient transportation. If it is planted in early spring, the east-west sunny border is the main. In addition to covering the greenhouse film, straw should be covered in time when the external temperature is less than 5 degrees Celsius. Autumn extension of seedlings in rainy days to do a good job of rain protection, if the temperature is higher than 35 degrees, it should be cooled in time. When more than half of the seeds are white, they can be sown. Water should be thoroughly watered before sowing. After the water is completely seeped, cover about a centimeter of fine soil, and then seal it with plastic film. Maintain the temperature and humidity of the seedling bed and speed up the emergence of seeds.

4. Pay attention to management

Before the emergence of hot pepper, the temperature should be kept at about 30 degrees during the day and 20 degrees at night. Then after emergence, when the seedlings grow two or so true leaves, the temperature decreases by about 5 degrees during the day and night. Then after the heart of the seedlings is broken, until before the five true leaves, the temperature during the day is kept at 25 degrees, and the temperature difference between day and night is about 10 degrees. Before grafting, usually do not water, if the seedbed is really too dry, then appropriate watering. However, we should pay attention to control the amount of water, to avoid more water retting roots. During the seedling growth period, targeted fertilization should be carried out according to the shape of the true leaves of the plant, mainly foliar fertilizer.
