Key points of apricot management in spring

The fruit setting rate of apricot itself is low, and the resistance of apricot to low temperature in budding and flowering stage is low, if there is low temperature, rain and snow in flowering, it will suffer frost damage, resulting in falling flowers and fruit, so the management of apricot in spring is very important. So how to manage apricot trees in spring? Come and have a look with the editor.

1. Delay florescence

In order to pick the heart in summer in the middle of winter, the accessory shoot flower bud should be used to set fruit, which can effectively improve the flower rate and natural fruit setting rate, the ground temperature can be reduced by watering in early spring, the blooming of tree trunk can be delayed, and the period of low temperature freezing injury can be avoided. This can reduce the freezing damage to flowers and significantly improve the fruit setting rate. It can also be sprayed with low concentration of salt water before germination, which can enhance the anti-freezing ability of flower organs and delay flowering.

2. Topdressing at flowering stage

The topdressing of apricot trees in spring is carried out half a month before flowering, mainly with quick-acting nitrogen fertilizer, and the specific amount of fertilizer application should be based on the actual conditions of the tree, such as tree potential, tree age, soil and so on. The method of topdressing is to mix the fertilizer after opening a shallow ditch on the tree plate, cover the soil immediately after fertilization, and then water it. In addition to topdressing at flowering stage, irrigation should also be carried out during persistent drought in spring, mainly when flower buds sprout no later than half a month before flowering, because this watering can not guarantee the need for flowering and fruit setting, and can delay flowering and reduce the harm of late frost.

3. Florescence management

The flowering management of apricot mainly includes flower thinning and fruit thinning, promoting flower insemination and anti-freezing during flowering, but there is nothing like flower thinning, and the phenomenon of falling flowers in apricot itself is more serious, so it is necessary to take measures to protect fruit, if there are invalid flowers, just keep a reasonable load. And fruit thinning is very necessary, the package, residual fruit and abnormal fruit need to be removed in time. The promotion of pollination can only be carried out manually or by releasing bees when conditions do not permit, because apricot trees have a large amount of pollen, generally sunny weather and pollination varieties, pollination is not a problem. And anti-freezing is generally to improve smoking, coverage and other measures to prevent.

4. prevention and control of diseases and insect pests

In the active period of diseases and insect pests in spring, the effect of controlling diseases and insect pests is also more obvious. the second is to ensure the normal growth and development of apricot trees. Apricot pests are mainly aphids and scale insects in spring, and diseases are mainly gum disease, brown rot, perforation and so on. Prevention and control can be combined with agricultural control, physical control and chemical control and other measures for comprehensive control.
