Fruit Tree Cultivation Techniques: What Precautions Should Be Taken After Harvest?
There are many varieties of fruit trees, and common ones include peach trees, pear trees, plum trees, apple trees, and so on. When cultivating fruit trees, not only must you master various key points during the planting period, but the management work after harvest is also very important. Let's take a look below at Fruit Tree Cultivation Techniques: What Precautions Should Be Taken After Harvest?
I. Fruit Tree Cultivation Techniques: What Precautions Should Be Taken After Harvest?
1. Protect the leaves from damage
The larger the leaf area of a fruit tree, the more organic nutrients and energy sources are produced during photosynthesis, so that the flower buds formed are fuller and the branches are more substantial. So how do you protect the leaves? After the fruit is harvested, specialized insecticides and fungicides should be sprayed.
2. Spray a certain amount of foliar fertilizer
After the fruit is harvested and before the fruit trees shed their leaves, an appropriate amount of foliar fertilizer can be sprayed. The main advantage of foliar fertilizer is that it takes effect relatively quickly, and only a small amount is needed to achieve very good results. Spray once every half a month, so that the nutrients needed for the later growth of the fruit trees can be supplied, allowing the tree body to store nutrients and reducing the occurrence of early aging and early dropping.
3. Apply base fertilizer early
After the fruit trees are harvested, base fertilizer should be applied early, as this plays a very important role in high yield and stable quality of the fruit trees. The base fertilizer used is mainly farmyard manure rather than organic fertilizer, because organic fertilizer decomposes relatively slowly and its fertilizer effect is released relatively slowly.
The specific amount of base fertilizer to use should be determined according to the variety of fruit tree, tree age, and growth vigor of the fruit tree, and growers can arrange it reasonably.
4. Deep plowing work
Before the soil freezes is the best period for deep plowing in the orchard. Deep plowing is beneficial for the soil's physical and chemical properties, improving soil fertility, and turning some insects and eggs that overwinter in the soil to the surface to freeze to death.
5. Cleanup work
Weeds, dead branches, fallen leaves, and diseased or pest-damaged fruit in the orchard are gathering and overwintering places for pathogens and pests, so cleanup work is very necessary and can reduce the occurrence of pests and diseases.
II. What Are the Key Points of Fertilizing Fruit Trees?
1. Fertilization should be based on actual conditions
Fertilizing fruit trees should be determined according to soil conditions, tree age, fertilizer type, and so on. If the soil is relatively poor garden soil, more fertilizer is needed; if the soil fertility is good, then less fertilizer can be applied. During the young tree stage, more fertilizer is often applied, while for mature trees the number of fertilizer applications can be reduced.
2. The fertilization period should be appropriate
Base fertilizer is generally applied from autumn to early winter, and applying it a bit earlier is beneficial for root regeneration after root cutting and for releasing fertilizer effects. For topdressing, fertilizer should be applied reasonably according to several different periods, such as before and after flower bud differentiation and during the fruit swelling period.
3. Choose suitable fertilizers
Chemical fertilizers generally refer to nitrogen, phosphorus, potassium, and trace element fertilizers, and whichever is lacking should be supplemented. For organic fertilizer, choose fertilizer that has been thoroughly decomposed to reduce the breeding of bacteria and so on.
In summary, after fruit trees are harvested, there is not nothing to do; the management work is also very important and has an important impact on fruiting again the following year.
