Tangshan Bingli processing factory takes you to know: how to cultivate chestnut seedlings reasonably?

How to cultivate chestnut seedlings reasonably? Tangshan Bingli processing plant tells you that the first is the planting environment of chestnut, and the second is the cultivation technology of chestnut. One is the choice of garden. The second is the choice of species. The selection of varieties should be based on local excellent varieties. At the same time, early, middle and late varieties should be reasonably matched. The third is the configuration of pollination trees. Chestnut mainly relies on wind-borne pollen, but due to the phenomenon of male and female flowers and self pollination, a single variety often has poor pollination and empty bracts. Therefore, a new chestnut garden needs to prepare some pollination trees, which can be controlled at about 10%. Fourth, reasonable close planting. Reasonable and appropriate close planting is the basic technical measure to improve unit yield. 30-40 plants are planted per mu in plain chestnut orchards and 40-60 plants per mu in mountain chestnut orchards. The plan is that chestnut orchards with high planting density can be planted with 60-111 plants per acre, and other staggered thinning will be gradually started in the future.

Fertilization of chestnut seedlings is basically carried out from early October to late September. The fertilizer is excavated along the periphery of the crown ring groove, and the addition of phosphorus nitrogen balance potassium is decomposed. They are usually 15-20 kilometers long and fertilize chestnut trees together with photosynthetic membrane, which is conducive to the absorption of chestnut roots, so that chestnut trees have a process of absorbing light energy and fertilizer. Chestnut, also known as xerosis, is a disease that first damages branches. The smooth bark is stained with yellowish brown round or irregular water, or has slight bending damage. This is preventive. Except for some decay, it needs to be disinfected and preserved with alkaline water or salt water. Multiple transplants of chestnuts are a common method of this kind of bark transplantation. The traditional method is a forked transplantation segment with a diameter of 3-5cm.

Sawing or cutting as a lubricant, cut with a flat knife, so that the residue of some branches is the top of 2-4 full buds of the scion, shave the base on the ear shaped slope of chestnut seedlings, about 15cm long, suspended at 5cm, and then thick ears, 1/2 more than the cost, 1/2 less than the thickness of each of our cutting knives, from the floating side to smooth, the horizontal arrow indicates the shape, etc., the leather knife Prys the wood to cut the scion, and the straight stab interface mode does not leave due to exposure, Then do not wrap the sunshine with plastic strips. If the root is very thick, multiple scions may be required during insertion, so that the healing time interface is easier to appear. Chestnut seedlings are sprayed once every 7 days, and the early control area is sprayed 2-3 times according to the spraying situation.
