How to fertilize green plum skillfully? What are the key points of planting techniques?

Green plum is a kind of fruit with unique taste, which tastes sour and crispy, which makes many people can't stop. There are many varieties of green plum, in addition to some edible varieties, there are some can be planted for ornamental. Green plum can also be used as medicine after salinization, which has the effect of promoting fluid and relieving cough. Green plum is planted in many places in our country. Let's take a look at how to fertilize green plum skillfully. What are the key points of planting techniques?

First, how to fertilize green plum skillfully?

Rational fertilization should be carried out. The root system of plum is shallow, and the unfruitful tree can be combined with weeding and shallow ploughing in spring to promote root growth; at the end of autumn, combined with buried application of organic fertilizer, deep ploughing of 12-15 cm can promote the dormancy of fallen leaves. Adult trees can plough and improve the soil every year after autumn, combined with the application of organic matter fertilizer, and rotate between plants and rows year by year. The fertilization of plum trees should also be carried out reasonably according to different tree ages and different growth periods. The fruit tree focuses on three links, that is, pre-flowering fertilizer: mainly organic fertilizer, combined with available fertilizer, fertilizer accounts for 60% of the whole year, applied in "the Beginning of Winter" to "the Winter Solstice". Spray Caohuawang No. 3 to promote strong flowers, spring shoots grow normally and reduce fruit drop. Post-fruit fertilizer: mainly organic fertilizer, combined with some available fertilizer, the amount of fertilizer accounted for 35% of the year, applied after fruit harvest. Combined with spraying plant electronic fertilizer to exert fertilizer effect for super long. In order to restore the tree potential, promote the thick green leaves, enhance the assimilation, enrich the branches and promote the flower bud differentiation. Strong fruit fertilizer: mainly potash fertilizer, combined with part of nitrogen fertilizer, the application rate accounts for 5% of the whole year, applied in the young fruit stage. Combined with spraying Zhuangguotiling, it can coordinate nutrition, reduce fruit drop, promote fruit enlargement and enrich spring shoot growth.

Second, what are the key points of green plum planting techniques?

1. Land selection and preparation

The growth habit of green plum is warm, and the cold tolerance is strong, so the planting land will generally be selected in the sunny organizing committee where the soil, water and air are not polluted, and at the same time, the soil fertility should be sufficient and drained to do well. Good permeability, more humid soil to plant. After selecting the site, dig deep into the planting holes, sprinkle sufficient fertilizer in the holes, cover them with a layer of fine soil, and finally plant them.

2. Reasonable close planting

The tree shape of green plum is relatively large, so in general, only about 40 to 55 trees can be planted per mu, of which the planting density is about four meters between rows and about three to four meters between plants, depending on the fertility of the soil and the varieties of green plum trees. If you want to increase the early fruit, close planting can be carried out appropriately. The density of four meters between rows and three meters between plants was used for colonization.

3. Watering method

After planting, that is, when there are a lot of Rain Water in summer, the fields are often in a state of high temperature and humidity, so we should carry out timely drainage to enhance soil permeability, followed by fruit gestation in spring. we should water the right amount and prepare for frost prevention at the same time.

4. Pruning and shaping

For young fruit trees, we have to keep pruning before the shape of the tree is formed, so that green plum can grow better. Generally speaking, some branches that are unfavorable to the light should be trimmed, and the dry or messy branches should also be cut off so as not to affect the beauty of the tree shape. Adult green plum trees generally talk about withered branches, dense branches, diseased branches, insect branches, weak branches, sterile branches and so on, which can improve the light, at the same time let it grow new branches and leaves, and increase the yield to a certain extent.

5. Pest control

The main diseases of green plum are anthracnose, scab, gum disease and so on. These diseases are basically caused by high temperature and high humidity or low temperature and high humidity or even high temperature and low humidity. In general, we can use carbendazim to control. The most common pests are aphids, heart-eating insects, longicorn beetles and scale insects. We can usually use dimethoate milk to guard against poisoning.
