Tian tou joke

Seeing that half of the fruit trees have been fertilized, I immediately thought of the joke that "the doctor discussed a drop of water". Since this problem is related to fertilization, we can get the result we need from the perspective of fertilization methods: no!

The old saying "I have never eaten pork, but I have seen pigs walk" is very suitable to describe this problem. If you don't fertilize the fruit trees yourself, you can witness the process of fruit farmers' friends fertilizing the fruit trees. If you can sit at the end of the ridge and chat with your fruit farmers' friends, you will know that there are two kinds of fertilization methods used by fruit farmers' friends: soil fertilizer and root fertilizer, in which soil fertilizer is divided into ring ditch, Xie ditch and hole shape.

When terraced orchards or fertilizer sources are not enough and manpower is sufficient, many fruit farmers mostly use strip furrow fertilization method when fertilizing fruit trees, and this fertilization method happens to be semi-fertilization method. When ditching, only fruit trees outside the drip irrigation line will be divided into east, west, north and south directions. This year, north-south furrow fertilization will be needed, and next year, east-west fertilization will be needed. However, in terraced orchards, due to the limitation of fruit surface, it is impossible to apply base fertilizer in four directions in some places.

In the orchard with zonal furrow fertilization, when the fruit trees absorb nutrients, the roots with fertility supply will grow stronger. However, when distributing nutrients, fruit trees will not be biased towards those fruits growing in the north-south direction because the roots in the north-south direction are rich in nutrients, but will show the attitude of "the palm is meat and the back of the hand is meat", and the fruits in the east, west, north and south will get corresponding nutrients.

In a word, if fruit farmers use semi-fertilization, the fruit on the fruit tree will not be half good and half bad, and if conditions permit, it can't be fertilized in the same direction every year. Only by changing the direction every year or applying fertilizer by other methods can the root system of fruit trees be evenly distributed and robust, thus ensuring a good growth environment for fruit pairs.
