Cultivation techniques of fruit trees: what are the points for attention after fruit harvest?

There are many kinds of fruit trees, such as peach, pear, plum, apple and so on. The cultivation of fruit trees should not only master all kinds of key points during the planting period, but also the management after fruit picking is also very important. Let's take a look at the cultivation techniques of fruit trees: what are the matters needing attention after fruit picking?

First, fruit tree cultivation techniques: what are the matters needing attention after fruit harvest?

1. Protect the leaves from the wound

The larger the leaf area of fruit trees, the more organic nutrients and energy sources during photosynthesis, so that the flower buds will be full and the branches will be full. So how to protect the leaves? Professional pesticides and fungicides should be sprayed after fruit harvest.

2. Spray a certain amount of foliar fertilizer

Appropriate amount of foliar fertilizer can be sprayed after fruit harvest to before the leaves of fruit trees fall. The main function of foliar fertilizer is that the effect is relatively fast, and a good effect can be achieved with only a small amount. Spraying every half a month, so as to achieve the nutrients needed for the later growth of fruit trees, so that the trees can store nutrients and reduce the occurrence of premature senility and premature fall.

3. Apply base fertilizer early.

Base fertilizer should be applied early after fruit tree harvest, which plays a very important role in high yield and stable quality of fruit trees. The use of base fertilizer is mainly farm manure rather than organic fertilizer, because the decomposition of organic fertilizer is relatively slow, and the fertilizer effect is relatively slow.

The specific amount of base fertilizer should be determined according to the variety, age and growth of fruit trees, and growers can make reasonable arrangements.

4. Dig deep into the work

Before the soil is frozen, it is the best time to turn the orchard deeply. Deep ploughing is good for soil physical and chemical properties, improving soil fertility, turning over some overwintering insects and eggs and freezing to death.

5. Clean-up work

Weeds, withered branches, fallen leaves, diseases and pests in the orchard are the gathering and overwintering places of germs and pests, so cleaning work is very necessary to reduce the occurrence of diseases and insect pests.

What are the main points of fertilization for fruit trees?

1. Fertilization should be based on the actual situation

The fertilization of fruit trees should be decided according to soil conditions, tree age, fertilizer types and so on. If the soil is a relatively poor garden soil, you need more fertilizer, and if the soil fertility is good, you can apply less fertilizer. There are many right and wrong in the period of young trees, but adult trees can reduce the times of fertilization.

2. the period of fertilization should be suitable.

Base fertilizer is generally selected from autumn to early winter, and it is good for root regeneration and fertilizer effect to be carried out a little earlier. Topdressing should be applied reasonably according to several different periods, such as before and after flower bud differentiation, fruit expansion and so on.

3. Choose the right fertilizer

Chemical fertilizers generally believe in nitrogen, phosphorus, potassium and trace element fertilizers, which are missing and which are replenished. Organic fertilizers choose mature fertilizers to reduce the growth of bacteria.

To sum up, it is not that there is nothing left to do after fruit harvest, and management is also very important, which has an important impact on re-fruiting in the coming year.
