What kind of fertilizer is applied to chili trees?

Pepper is one of the essential dishes, which has the functions of sterilization, antisepsis, seasoning, nutrition, cold expelling and so on. Therefore, adding a little chili to your daily menu is good for your health. At present, there are also many people who have the experience of growing chili peppers, so, what kind of fertilizer do chili trees apply?

What kind of fertilizer should be applied to chili trees?

Pepper tree base fertilizer can be applied with stable fertilizer, phosphate fertilizer, calcium superphosphate, etc.; urea can be used as seedling fertilizer after transplanting for about 15 days; compound fertilizer is generally applied during the growing period; ammonium sulfate or calcium superphosphate is applied at the initial stage, 0.2% potassium dihydrogen phosphate can also be used for foliar spraying.

Second, the planting technology of hot pepper

1. Soil preparation and fertilization

Continuous cropping of chili is not allowed, nor can it be cropped with eggplant, tomato, potato, tobacco and other crops of the same family. The cultivation of pepper plots should have good drainage, convenient drainage and irrigation, and require deep ploughing. It is best to do winter ploughing, leisure permafrost, in order to improve the soil and eliminate overwintering pests and pathogen spores. The growing period of pepper is long and its root system is weak. in order to make it blossom and bear fruit continuously, it must have good soil and nutrition conditions, 10-15 cm deep before planting, 5000 kg of barnyard manure per mu can be mixed with 15-20 kg of calcium superphosphate, and short irrigation and short drainage can be used as ditches and ditches to communicate with each other so that there is no water in the field after rain.

2. Planting management

Pepper should be planted in an appropriate period to promote early rooting, and early seedling emergence is the main principle of management during planting period and after planting. It is appropriate to cultivate soil and seal ridges gradually after shallow soil cover during planting, and only rely on drought squatting seedlings will damage the root system after planting. So pepper seedling stage management should be small squatting seedlings or not squatting seedlings to promote to the end.

3. Planting density

The plant type of pepper is compact and suitable for close planting, especially the green pepper growing until autumn. Proper close planting is beneficial to early ridge closure. Due to the shading of the surface cover, small changes in soil temperature and soil humidity, and the root system will not be exposed to the sun after rainstorm, the production density of green pepper is 3000-4000 holes per mu, row spacing 50-60 cm, plant spacing 25-30 cm, usually double plants or 3 plants with 1 hole. High yield can be obtained by planting methods such as single row close planting with large ridge, same close planting with large ridge and double row planting with large ridge.

4. Weeding and fertilization

After planting and surviving, the pepper should be ploughed once in time, the plant should be ploughed once more before the plant is closed, the middle ploughing should be combined with weeding and soil cultivation, and the seedling fertilizer should be applied on a sunny day after planting. Each time should not be too much or too dense, otherwise it is easy to cause overgrowth and delay flowering and fruiting, and more fertilizer should be applied to promote fruit growth after one or two layers of fruit. After the fruit is picked, it is necessary for the soil to have sufficient fertilizer and water plants in order to grow and bear fruit normally.

5. Drainage and irrigation

The phenomenon of fallen leaves and dead plants of hot pepper will be quite common if it rains heavily before the soil is dry after watering, especially during the period from fluctuation to the Beginning of Autumn, so the irrigation time must be determined according to the weather forecast during irrigation. the irrigation depth should not exceed 3/4 of the border ditch and should be carried out at night or early in the morning.

6. Harvest and retain species

As a fresh food, most green fruits of chili peppers can also be harvested red fruits, while dried chili peppers must harvest red ripe fruits, which must be harvested in time or affect plant growth and fruit. the method of plant selection combined with fruit selection can be adopted in pepper seed selection. that is, according to the characteristics of varieties in the field, the standard plant is selected as the remaining plant, and the first layer fruit is harvested and listed as early as 2-4 layers of fruit as seed fruit. After red ripening, the fruits with the characteristics of this variety were further selected when harvested. The picked fruits were laid out in a cool place and ripe for 5-7 days, and the seeds were cut and dried and stored.

There are many kinds of fertilizers for chili peppers, and the fertilizers needed for the growth of chili peppers are not the same. I hope the above content can help you all.
