What are the advantages of Japan's apple industry to the extreme?

We know that the content of organic matter is an important indicator of soil fertility, and organic matter is the main source of soil nutrients, which can promote the formation of soil structure, improve soil physical properties, and improve soil fertility and buffering performance. At the same time, humus in organic matter has physiological activity and can promote crop growth and development. Humus in organic matter also has complexing effect, which is helpful to eliminate soil pollution.

Soil organic matter content and management system in Japanese orchards: We learned from our investigation in Japan that not only the apple orchards of Nakazawa Zhuojia in Nagano Prefecture have high organic matter content, but also most of the apple orchards in Japan have very high organic matter content due to the pursuit of super-high quality and special geographical conditions.

Almost all orchards in Japan grow grass. Problems existing in the soil management of apple orchards in China: It seems that the soil management of apple orchards in China is in a period of transition from chemical agriculture to organic agriculture. Many orchards blindly pursue high yield and use a large number of single chemical fertilizers, so the orchard soil is already very poor and the organic matter content is less than 1%. No matter how high the management level of such an orchard is, it is difficult to produce good fruit.

There are some orchards that produce thousands of kilograms of fruit every year. In winter, after the leaves are cleaned, they are taken home to burn the kang, and the pruned branches are taken home to cook in the stove. Even the weeds growing in the orchard are taken home to feed rabbits during the growing season, or they are simply removed and left on the roadside, and the soil is cleared.

There are so many things out of the orchard every year, and the soil is poorly supplemented, just a few bags of fertilizer. On the one hand, it produces tens of thousands of kilograms of things, and on the other hand, it supplements hundreds of kilograms of single chemical fertilizer. And year after year. In this way, the soil will become more and more barren, the nutrients will be seriously unbalanced, the organic matter content will decrease year by year, and various problems will breed.

For apple growers, maintaining a clean apple orchard is not only an indispensable job to get rich fruits, but also a kind of morality. But Kimura's orchard is just like a barren wild mountain. A few years before Kimura started planting apples, the surrounding fruit growers asked him to mow the grass, but he stubbornly refused to nod. At one time, the orchard was as barren as a dog with a skin disease.

why is it so barren? Everyone knows the fruit farmers nearby, because there is no pesticide sprinkled here, and the ecosystem has been restored here, returning to the real "nature". Since 1978, Kimura has never used a drop of pesticide or a pinch of fertilizer in this 8,8-square-meter orchard.

It is the secret that Kimura apples will not rot without using pesticides or even any organic fertilizers, but it is common sense for fruit farmers to use pesticides to cultivate apples. Kimura's dream of realizing nature farming, at least in the 198s, was absolutely impossible.
