What are the organic cultivation techniques of peach trees? What are the matters needing attention in organic cultivation techniques of peach trees

Fruit trees are perennial crops, the growth period after planting is as little as a few years ​​, most is 50 years, so the environmental conditions are closely related to fruit tree cultivation, the environment of fruit tree cultivation is roughly related to climate (air temperature, rainfall, sunshine, wind), soil (moisture, ventilation, topography, ground temperature, etc.), biological elements, pollination insects, diseases and insect pests, while labor, transportation and marketing are closely related to orchard harvest and management.

Organic cultivation of Peach trees

When 310 ping of farmland was purchased in 86 (located near the Hingling Mountains in Taichung), there were only 28 old peach trees (about seven years old), of which three were peach trees and 25 were March peaches. at that time, there was a lack of knowledge about the management and management of peach trees. moreover, the concept of organic cultivation is only half-and-a-half understanding, and can adhere to the instructions not to use chemical pesticides and chemical fertilizers. At that time, the peach trees in the garden were full of joy, thinking that there would be sweet and delicious peaches to enjoy in the near future. However, due to diseases, insect pests, finishing and improper fertilization, there were only 14 March peaches every other year. The ripe fruit was bitten by fruit flies, and the appearance was very beautiful and delicious, but all the rotting worms inside were so delicious that they needed to be bagged, but it was too late. It was only in this situation that the farmers said that the harvest could not be achieved without the use of pesticides. In the face of this adversity, it stimulates the desire to produce organic fruit.

As a matter of fact, the peach tree is a kind of fruit tree with strong vitality. it grows at the top of all fruit trees and forms the seedlings that germinated in July and August. After the Winter Solstice was grafted that year, they can blossom and bear fruit every other year. If you have good fertilizer management, there will be no problem in producing 30 jin. But its diseases, insect pests, fertilization, pruning (tree type arrangement) is a lot of thought. The following points are the practical experience and discussion on the production of organic peaches for more than six years.

1. Make good use of spray gun (incineration method)

The main results are as follows: (1) termites multiply on the trunk of peach trees in autumn and winter, especially old trees. At this time, the eaten part of the ant should be dug up, the termites should be burned with a spray gun, and the decayed part of the trunk should be carbonized.

(2) when the trunk is close to the ground, Ganoderma lucidum should be excavated, and the part of the trunk should also be carbonized. Observe for a period of time, if there is no longer, there will be no problem.

(3) shell pests: when this insect was first discovered, it was locally attacked by fire, and the effect was rapid. The above incineration method does not take time, the whole garden does not need to spray pesticides, and has no impact on the ecology.

two。 Make good use of apprentices to grow branches

In general, farmers deal with long branches by pruning, but organic growers must leave most of the long branches, and the bigger the better, because it is the strongest branch, the old branch is easy to grow bug and glue disease, but the growing branch has few such shortcomings. when the Winter Solstice pruning before and after pruning, all the branches of the previous year should be cut off (have begun to age), leaving only a few of last year's branches (larger fruit). In that year, the stout branches should be left first, and the branches should be flattened evenly. If it is too dense, the too small branches can be cut off, so that they will be strong and lively every year, although the new branches blossom a little more slowly and less. but organic peaches in natural farming methods are indeed rare, especially bagging well-done 's fruit, which is a delicacy in the world.

3. Multi-strain planting

In addition to the main strains in the garden, all the current strains can also be grafted to cross the peach blossoms in the garden. Although the single strain is not bad, it is believed that multiple strains can produce eugenic results. (the idea provided by Mr. Liu Tianhao, a farmer, has been proved to be feasible.)

4. Other fruit trees are planted between peach trees and peach trees, so if a peach tree produces diseases and insect pests, it is not easy to spread, and the treatment and control are relatively simple.

5. The use of bacterial fertilizer made of beneficial microorganisms, so that beneficial bacteria become the dominant population in the garden, the incidence of diseases is naturally reduced.

6. Deliberately cultivate into an ecological garden, so that the pests in the garden will be naturally eliminated by natural enemies, and there will be no caterpillars crawling all over the trees.
