Three measures for Spring Management of Cherry trees
The cherry in the first fruit of spring is in bloom. How to manage the cherry tree well in spring, we should pay attention to the following three measures: first, like other plants, cherries need a lot of mineral elements in the process of growth and development. such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, boron, zinc and so on. Lack of these.

Spring Management of Young Cherry Trees
The spring management techniques of young cherry trees are summarized as follows: 1. Fertilization. Before germination, urea 50g was applied to the plants, and sufficient thawing water was poured at the same time. 2. pollination. Big cherry is generally cross-pollinated species, few self-pollinated species, planting not only with pollinated trees, flowering also take pollination measures, generally artificial point...

Planting methods of Cherry in Spring
Cherry planting is generally planted after soil thawing in spring to before seedling germination, mostly from mid-late March to early and mid-April, near before germination. When planting, we should pay attention to the following two points: 1. Seedling selection and treatment. Before planting, we should choose strong seedlings with full bud eyes, developed root system and no diseases and insect pests. And then put the seedlings.

Sunshine is beneficial to pollination and fertilization of litchi and longan.
Experimental research and production practice have proved that the pollination of litchi at flowering stage is the guarantee of high yield of litchi, and the honey brewed by bees collecting pollen is also a natural health food for human beings. In order to prevent bee poisoning and honey pollution, ensure that there are enough workers to collect nectar, improve the effect of pollination and protect human health.

Calcium application can prevent litchi from cracking.
In recent years, litchi (glutinous rice, cinnamon, March red, green yarn, sweet rock, etc.) fruit cracking phenomenon is more common, litchi fruit cracking often occurs in the fruit expansion period, the normal year is generally 20% to 30%, serious up to 50%. There are many domestic reports about the cause and mechanism of litchi fruit cracking, among which many researchers mentioned.

Planting methods for high yield of litchi
Site selection and planting: for high-yield cultivation of litchi, hills or slopes with open terrain, loose and fertile soil, deep soil layer and water source should be selected as ideal development and planting gardens. Litchi mycorrhiza is good for air, so we should loosen the soil, improve the soil, loosen and aerate in order to promote the development of root system. Soil fertilization is based on the principle of frequent application and light application. Spray in time.

Clever pruning of apricot trees can delay flowering
The buds of apricot trees have strong prematurity and high recovery ability. if they are properly re-pruned in winter and pruned in summer, secondary shoots can be produced for 2 or 3 times in summer and autumn. The flower buds of different developmental stages will be born on the new shoots in spring, summer and autumn, and the flowering period in early spring will be greatly prolonged and the number of frosts will be reduced.

Causes and countermeasures of rotten apricot fruit in greenhouse
The reason for fruit rot is lack of light in the greenhouse for a long time in cloudy or rainy or snowy days, and there is a lot of dust on the surface of the greenhouse film, resulting in insufficient light and excessive humidity in the greenhouse. Young fruit grows in dark and moist air for a long time, which is easy to cause rotten fruit. The indoor temperature in the greenhouse is too high in the young fruit stage of apricot, if the indoor temperature exceeds 28 degrees Celsius.

Production technology of green fruit and early-maturing apricot
June is the ripe picking period of apricot fruit and the physiological differentiation and formation period of flower bud, and it is also the high incidence period of many diseases and insect pests. It is important to improve the quality of apricot fruit, promote flower bud differentiation and control diseases and insect pests. First, proper pruning: first of all, thinning out dense branches, picking the retained new shoots, so that you can...

Cultivation techniques of plum and apricot
1. High standard garden 1. Garden selection: apricot is a kind of tree species that is tolerant to early and intolerant to waterlogging, barren and fond of light, and is vulnerable to late frost at flowering stage. Therefore, the founding of the people's Republic of China should be selected in the back Phoenix to the sun, the terrain is higher, good drainage deep soil plot. 2, choose strong seedlings: high-quality strong seedlings ensure the survival rate and high yield.

About the most important summer pruning of apricot trees
In view of the low fruit setting rate of apricot trees in greenhouse, it is suggested that growers should grasp the artificial pollination at flowering stage from three points when cultivating apricot trees in greenhouse. The specific methods are as follows: 2-4 days before artificial pollination, buds with budding and normal development were collected from selected varieties with high pollination affinity.

Greenhouse apricot trees do a good job of management and promote development in spring
The fruit development period of apricot in winter warm greenhouse is from mid-February to the end of April, which is divided into three main development stages: the first stage is apricot first rapid growth period and new shoot growth period, the time is 28-34 days; the second stage is hard core period, the time is 8-12 days; the third stage is apricot fruit second rapid growth period and new shoot growth period, time.

Flower and Fruit Management of Apricot
First, artificial pollination of apricot trees depends on bees and other pollination. However, experience shows that artificial pollination can increase the fruit setting rate by 3-4 times compared with natural pollination. Artificial pollination should be carried out in full bloom, because the apricot florescence is very short (5-7 days), should be prepared in advance. Apricot pedicel fragile and easy to break, pollination should be extra.

Technical measures to improve the fruit setting rate of apricot trees
First, select excellent varieties. Selecting the varieties with high complete flower ratio, strong self-fruiting ability, frost resistance, late flowering, early fruit and high yield as the main varieties is the key to improve the fruit setting rate. For example, Golden Sun, Kate Apricot and so on. In addition, early, middle and late maturing varieties can also be selected to reduce early spring frost.

To improve the fruit setting rate of apricot trees, rational fertilization is necessary.
"Yunda Quan Fruit" is a new special growth aid for the balance of vegetative growth to reproductive growth on fruit trees and fruit vegetables (such as tomatoes, eggplants, melons, etc.). Its main features are: ① non-toxic performance, so that the fruit does not leave any residual poison, to achieve pollution-free, become a green rest assured product. ② promotes flowers quickly and quickly.

Do a good job of pollination of apricot trees in time
Why apricot trees often blossom a lot, but seldom bear apricots? The main reason is poor pollination. In order to improve the fruit setting rate of apricot blossom, we must prepare in advance and do a good job of apricot flower pollination in time. The main varieties of apricot trees should be selected with natural pollination ability, low abortive flower rate and high natural pollination fruit setting rate.

Installation of apricot trees to grasp "ten tubes"
Because of its cold and drought tolerance, most apricot trees are planted on slopes with poor ridges, and because their roots are strong and spread all over the garden, it is difficult to ploughing and ploughing. In addition, the standard of soil preparation is not high, which often results in soil consolidation and poor permeability. prone to soil-borne diseases (such as root rot), difficulties in fertilization, hard ploughing and other phenomena.
