Growth and fruiting habits and pruning points of Kernel Apricot
1. Growth and fruiting habits of kernel apricot: 1. Weak branching ability: several long branches are produced after kernel apricot planting. After entering the fruiting stage, these long branches are rarely branched, and the natural growth often shows insufficient branches. 2. High germination rate: most of the buds can germinate no matter the long branches of kernel apricot are thrown or truncated.

Techniques of fertilization and Irrigation Management of Apricot
(1) after the new shoots stopped growing from September to October every year, sufficient basal fertilizer was applied, mainly organic fertilizer such as stable manure and chicken manure, combined with a certain amount of quick-acting fertilizer. the amount of fertilizer should be determined according to the size and growth of the tree, usually 30 kilograms of organic fertilizer per plant, plus about 0.5 kilograms of special compound fertilizer for fruit trees. Cute.

Winter pruning of apricot trees
As the saying goes, "apricot trees do not harvest in ten years and nine years", in addition to the low fruit setting rate, it is mainly due to the great decrease in the ability of apricot sprouting and flowering to resist low temperature, which is less than-3.9 in bud stage, less than-2.2 in florescence, less than-0.6 in young fruit stage and more than 30 minutes in low temperature period. Freezing injury is easy to occur. So...

The management of apricot trees after fruit picking should keep up
Symptoms Apricot brown rot has two symptoms. A harmful near-mature fruit, initially forming dark brown, slightly depressed round lesions, then rapidly expanding, soft rot, with yellow-brown velvety particles, whorled or irregular, damaged fruit more early fall off, rot, a few hanging on trees to form dead fruit. Another harmful fruit...

Transformation of low-yield apricot orchard
The characteristics of low-yield gardens include low-yield young tree orchards and low-yield old tree orchards. The apricot orchard whose output is lower than the average yield of this area year after year, or lower than the output of similar orchards around it, is a low-yield orchard. The main results are as follows: 1. In the young tree orchard in full fruit period, the tree potential is weak, the crown is small, the expansion is slow, the branch quantity of the extended branch is small, and the fruiting branch.

Cultivation techniques of Apricot
The main results are as follows: 1. The garden should be built on sandy loam soil with deep and fertile soil layer and can be irrigated and drained, but not suitable for waterlogged land, heavy saline-alkali land and continuous cropping land. Pollination trees should choose varieties with the same flowering period or earlier than the main varieties, and the ratio of pollinated varieties to main varieties is generally 1:6-8. Planting density plain plant row spacing 3 m × 4-5 m, in.

Pest Control of Apricot cultivation
Apricot wasp: the larva overwinters in the apricot kernel or in the apricot nucleus on the branch, the female adult lays eggs between the nuclear skin and the almond, the spawning hole on the fruit surface is not obvious, slightly grayish green, sunken, sometimes there is apricot gum outflow from the spawning hole, and the egg period is about 10 days. The hatched larvae eat almonds in the nucleus, resulting in a large number of fruit drops. Around the beginning of June.

Cultivation and Management of Chinese Chestnut
Castanea mollissima is a famous fine dried fruit tree of Fagaceae. Chinese people have thousands of years of cultivation history and accumulated rich experience. It occupies an important position in the economic life of our people. Chinese chestnut is rich in nutrition and delicious. It can be eaten fresh, fried, cooked and made all kinds of snacks and dishes. It has the characteristics of sweet, fragrant and waxy.

Summer fertilization of Chinese Chestnut
In order to improve the yield and quality of Chinese chestnut, chestnut trees should be fertilized in summer. there are two main fertilization methods: soil fertilizer method: the soil fertilizer method is better in the chestnut orchard with thin soil and serious lack of fertilizer. In the chestnut crown drip line, dig a circular ditch for fertilization, 25 cm wide and 2 cm deep.

Control methods of insect pests in Chinese chestnut
1. Chestnut gall wasp, also known as chestnut tumor peak, adult head and abdomen dark brown, antennae filiform, brown, chest dilated, pitch black, lay eggs in the bud from June to July, and the larvae grow in the bud and overwinter. Spring buds sprout short branches, damaged branches or petioles and other inflated adult galls (tumors), withering branches and leaves and weakening the tree.

Supplement micro-fertilizer to Chinese chestnut after production
The main reason for the low yield and high empty bract rate of chestnut orchard is that it is not applied or sprayed with boron fertilizer in the process of management. When the content of available boron in soil is less than 0.5 parts per million, it will affect the normal fertilization process of Castanea mollissima, resulting in the early stagnation of embryonic development, thus forming the empty bud of Castanea mollissima. It can be grasped in production.

Zinc and Boron should be supplemented in Postharvest Chestnut
At present, the yield of most chestnut orchards is not high, the plant yield is only 4-5 kg. Many Chinese chestnuts hang fruit trees with bracts and no chestnuts (that is, empty buds). The reason is that in addition to extensive management, it has a great relationship with the application of zinc and boron. Practice has proved that the supplementary application and spraying of zinc and boron micro-fertilizer after fruit picking of Chinese chestnut can promote flower, differentiation and improve flower quality.

Post-harvest management of Chinese chestnut
(1) Disease control 1. Dry blight, also known as chestnut blight, chestnut carcass blight, chestnut skin rot, is a fungal disease. Most of the pathogens invade from the wound, mainly harming the trunk and branches, but it is not easy to find at the initial stage. If you scrape the bark lightly with a knife, you can see small reddish-brown spots. After the spots are connected into blocks, the bark surface is raised.

Chestnut "empty shell" is well controlled
Chestnut "empty shell" is also called "empty canopy", empty shell rate can reach 30%~90%, affecting chestnut yield. The main reasons for producing empty bract of chestnut are: ① poor pollination and fertilization in flowering stage of chestnut. (2) Boron and available phosphorus deficiency in soil. 3. Influence of other factors. One is variety, different variety, male and female inflorescence quantity is different, all...

Control of Castanea mollissima Red Spider
The Chinese chestnut red spider is called the needle leaf small claw mite, harms the Chinese chestnut leaf, causes the leaf to fade into the yellow and white small spot, serious leaf scorch turns brown, causes the reduction in yield. The winter eggs overwintered on the leaf scars, coarse bark crevices and branches on the back of 1-4-year-old branches, and began to hatch from late April to early May the following year, when the chestnut buds were sprouting.

Fertilization skills and key points of Chestnut Orchard
Chestnut dry blight, also known as chestnut rot, carcass blight, chestnut blight and so on, is an important disease on chestnut, which mainly harms the trunk and main branches, often causing trunk and main branches to rot until the whole plant dies. The pathogen of chestnut dry blight mainly overwintered in diseased branches by mycelium, conidia and ascomycetes.

High yield planting techniques of Castanea mollissima
If we want to have a high yield in the coming year, we must break the practice of planting Chinese chestnut, otherwise it will affect the yield and quality of Chinese chestnut in the following year. In particular, chestnut trees in the full fruit period should do a good job in post-harvest management, focusing on the following four points. 1. The winter pruning date for winter pruning chestnut trees should be arranged in mid-December.

Comprehensive high-yield technology of Chinese chestnut
1. Close planting and reasonable close planting can not only increase the early yield and obtain economic benefits as soon as possible, but also facilitate the intensive management of orchards. Planting density: the plant row spacing is generally 2m × 4m and 3m × 4m or 3m × 5m. The specific density depends on the characteristics of rootstock, scion or site conditions. It can be recovered within 6 years after planting.
