Latest Technical Methods and Tutorial for Sea Buckthorn Field Management
Sea buckthorn is a common wild fruit tree in the southwest and northwest regions, able to survive on saline-alkali land. Its fruit is rich in vitamin C, so it is favored by the market, and people have begun to cultivate it as an economic fruit tree. Due to the particularity of its growing environment, its planting and management work differs from that of many fruits, and if it is planted in different regions, the management content also differs. Today we will specifically talk about management after growth.
1. Pruning
Sea buckthorn branches are rather scattered, and it is mostly a shrub with no obvious main trunk, so the tree shape must not be allowed to become too messy, to make management convenient. When it grows to more than 2 m, it should be pruned, mainly cutting crossed and horizontally growing branches. In dense areas, strong branches should be selected and kept, and the rest cut off. Generally, where branches are lacking, branches should be cultivated, and branches should be renewed in time, replacing them with new fruiting branches. Diseased and pest-infested branches should be cut off in time, and disease spots on the trunk should be scraped off.
2. Protecting flowers and fruits
For a abundant fruit yield, flower bud differentiation must be promoted, and more flowers must bloom so that more fruit can set. New shoot growth should be controlled; before fruiting, fewer new shoots may be retained, and too many should not be kept. In addition, flowers should be thinned; for clustered flowers, some should be thinned out. When there are extremely many flowers during the flowering period, the branches can be gently shaken. After fruit set, some densely clustered fruit clusters should be cut off to avoid the phenomenon of alternate bearing, or excessive flowering and fruiting leading to severe fruit drop due to malnutrition.
3. Diseases and insect pests
The main disease is shrinkage disease, a devastating disease. The pathogen will invade from wounds and the root system, so do not cause artificial wounds. Before planting, varieties with the strongest resistance and good adaptability to the environment should be selected. For treatment when disease occurs, mainly use 40% carbendazim suspension concentrate at 500 times dilution or thiophanate-methyl at 800 times dilution for root irrigation treatment. Once a month, carried out multiple times. The main insect pest is the apple small leaf roller, and 25% methamidophos at 2500 times dilution or 20% fenvalerate at 3000 times dilution should be sprayed for control.
4. Other management
Although the soil is resistant to barrenness, it is sensitive to phosphorus fertilizer demand, so phosphorus fertilizer can be applied as a top dressing. Planting should preferably not be too dense, with a plant spacing of 1.5 m and a row spacing of 2 m, and it can also be adjusted by oneself. Sea buckthorn is dioecious, so pollinator trees should be arranged between rows, roughly one male plant for every 3 female plants. Harvest in time to avoid the fruit being eaten by birds. Harvest when the color darkens, the flesh softens, and there is a fragrance. After harvest, store at a low temperature of 1 to 5 degrees.
The management details that should be done well after planting a sea buckthorn orchard are the above parts, but in practice there will be some changes under different environments, and more details should be paid attention to. At present, these are mainly the important contents. For anything not considered, you can consult experienced fruit growers yourself.
