In recent years, the market positioning of pepper has been improved, and the market demand for pepper has gradually increased, which has increased the enthusiasm of pepper growers. So what are the precautions for planting pepper? Today we mainly study the management points of pepper from March to May.
1. Plant protection
(1) Qingyuan
Spray with traditional stone sulphur mixture 3-5 Pom's degree; or use high-permeability insecticidal ovicidal agent plus fungicide to clear the garden.
(2) According to the different conditions during the growth period, the prevention of pests such as aphids, narrow ji worms, cotton aphids, prickly phoenix butterflies, wax worms, scarabs and other pests of the pepper tree, mainly based on prevention, can achieve twice the result with half the effort. For example, in 2018, the spread of locusts caused the loss of control of gray mold, which caused great losses to many pepper farmers. The fungi mainly control the damage of gray mold, pepper rust, anthracnose, and keratosis due to temperature and humidity.
Note: Be sure to find a qualified pharmacist to prescribe medicine, especially during the flowering period, pay special attention to it, otherwise it will cause falling flowers and even red particles. Most people think it is a physiological drop. In fact, there are reasons for this. There are many reasons for falling flowers and fruit drop, the upper and lower nutrition imbalance, that is, the lack of fertility, malnutrition caused by poor pruning; the poor shade of trees; the bad weather, such as low temperature; the medicine caused by improper flowering Harm; also has a certain relationship with the pepper strain. When the medicine is used, a growth regulator such as brassinolide, potassium dihydrogen phosphate or a foliar fertilizer may be added depending on the case.
2. Management of the growing season - less moving scissors and more hands
(1) Wiping
Generally, the base buds, the cut buds, and the main branches are competing, juxtaposed buds, and the fruit branches are slightly budded. If the bud is neglected in the spring, the autumn shear is a long vegetative branch that affects the healthy growth of nutrients and other branches.
(2) Pre-flowering
According to the characteristics of the spring climate, the pepper trees are inspected and pruned without cold or cold weather to ensure the balance of the above-ground and underground branches of the tree. For the long branches, the big head branches, the empty branches, the cross branches, and the friction branches, the corresponding branches are retracted, and the overlapping branches, the closed branches, or the auxiliary branches are combed.
(3) Topping
It is generally divided into light heart picking and heavy heart picking. It is mostly used for the shaping of young trees and the cultivation of young age tree branches. It is often used to pick up the heart, that is, pick up half a cent. The result is that the buds have good nutrient accumulation, the second germination time is late, and it is an extended head to continue to grow. The topping of the heart will be 2 - 3 buds all under the topping point, weakening the branches, and the nutrient accumulation is poor. Three buds sprout quickly, and nutrient accumulation is not as good as light heart picking. Generally, the topping of the vegetative shoots that have not stopped growing at the end of the first growth period in late May or early June may also be topped according to the plastic scale.
(4) sparse
The combing of the weak branches of the closed area, the grooming of the foot branches, the competition of the branches of the main side, the combing of the branches and the combing of the vegetative branches on the back, also pay attention to the eradication of the cut buds in a few days.
(5) pull the branch
This link is very helpful for the shaping of young trees and young trees, and plays a vital role in the vegetative growth and reproductive growth of the pepper trees. Direct use of pull branches can convert the vegetative shoots into nutrient accumulations into the result branches of the second year. Generally, when the branches are pulled, the side branches are gentle, conforming to the direction of the main branches, and the main branches are raised upwards to maintain a strong momentum.
3. Watering in the early stage of germination, conditional irrigation with biogas slurry is best
Watering can lower the ground temperature and prevent cold weather. It can also create favorable conditions for germination and speed increase after the ground temperature rises. The effect of watering before germination is particularly good. The corresponding situation in the later period is poor. At the end of April, at the beginning of May, the water was flooded with fertilizer, so that it was supplemented with nutrients and then added with water, which was conducive to the fruiting and fruit expansion.
The above is the main point of spring management of pepper, do you think it makes sense? Farmers with better experience are welcome to share your knowledge!
