Persimmon tree planting technology

Abstract

The invention belongs to the field of fruit tree planting and particularly relates to a persimmon tree planting technology. The technology comprises steps as follows: A, grafting: healthy persimmon tree branches are selected, end parts of the persimmon tree branches are immersed in a polysaccharide solution and then grafted to jujube tree branches which are 1.5-3 times as thick as the branches of a persimmon tree; B, after first frost, an aqueous solution of a mixed fertilizer is irrigated to roots of the persimmon tree according to the soil moisture content; C, on the winter solstice, the branches are pruned in winter, sick branches and weak branches of the persimmon tree are removed, and a trunk and branch growth positions of the persimmon tree are wrapped with gauze immersed with a baume-degree lime sulfur mixture or a 220-fold lime sulfur aqueous solution or a 15-17-fold crystal lime sulfur mixture; the outer layer of the wrapping gauze is covered with a film; D, in early spring, the gauze wrapping the persimmon tree is removed, and the baume-degree lime sulfur mixture is sprayed to a tree crown. Pest and disease damage is controlled by wrapping the non-fruit positions such as branches of the persimmon tree and the like with the gauze with pesticide substances, and harm to a human body and persimmons due to repeated spraying of pesticides is avoided.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, in particular to a technique for planting persimmons. Background technique [0002] Persimmon is sweet, astringent, cold in nature, and returns to the lung meridian. Persimmon is a fruit that people prefer to eat. It is sweet and delicious, and rich in nutrition. Many people also like to eat frozen persimmons in winter, which has a unique taste. The nutritional value of persimmon is very high. Compared with apples, except that the content of zinc and copper in apples is higher than that of persimmons, other ingredients are dominated by persimmons, and the vitamins and sugar contained in them are about 1-2 times higher than ordinary fruits. If a person eats 1 persimmon a day, the vitamin C intake can basically meet half of the daily requirement. At the same time, persimmon leaves have high medicinal effects. It is recorded in "Compendium of Materia Medica" that "persimmon is the fruit of the s...

Problems solved by technology

In the prior art, the control of the persimmon scale is mainly to spray insecticides on the trunk, branches and leaves of the persimmon tree, and even the fruit trees. This method affects the safety of people eating persimmons to a certain extent.

[0004] Another problem is that the fruit of persimmons is relatively astringent. In order to reduce the astringency of persimmons, it is generally necessary to evenly spray or dip the surface of persimmons with preservatives. It can maintain a certain hardness inside, prolonging the market sales cycle; or use a wooden stick to puncture the skin of the persimmon to remove the astringency of the persimmon, but this measure affects the sales of the persimmon and is not conducive to the long-term storage of the persimmon; Spray sweetener directly, but this causes great hidden danger to people's food safety
