When will the Dutch fragrant apricot mature?

Dutch fragrant apricot single fruit weighs 60 grams, larger fruit weight 90 grams, sugar content 16.7, enucleated, almond sweet edible. Shandong area matures from late June to early July, the planting range of fragrant apricot is wide, the growth is fast, the planting can bear fruit in the second year, and the benefit is good. It is an excellent variety of ecological picking garden and one of the rich projects with development prospects.

Second, what are the key points of planting techniques of fragrant apricot in the Netherlands?

1. The sparse technique and short cut of apricot planting.

Apricot is a strong light-loving tree species, and its own growth is very exuberant, which is easy to form competitive growth and make the fruit parts move outward, which is very disadvantageous to the formation of strong flowers and fruiting, so the fruit trees should be sparse mainly in the autumn tube after fruit picking. the pruning method of drawing large branches and depressing the height of the tree is adopted to promote the lower part and inner chamber to draw new branches and form short fruit branches and bouquet-like fruit branches. Of course, at the same time of thinning, we should pay attention to open the light path to ensure the uniform distribution of the retained main branches, and adopt the means of pulling, falling, distinguishing and supporting individual branches that can remain, so as to change the direction of the branches and make use of more fruit in the space; mop skirt branches, diseased weak branches and overdense branches can be removed at the same time.

2. Fertilization and irrigation of apricot planting.

In autumn, the apricot orchard can be topdressing 50 kg of available nitrogen fertilizer or 50 kg of urea per mu, and appropriate amount of phosphorus and potassium fertilizer can be applied to planting big trees. 5 kg of nitrogen, phosphorus and potassium mixed fertilizer can be applied around the tree pit. It is good to encounter rain after application. If the drought is serious in summer and autumn, we can strive to irrigate it from August to September. But we should pay attention to the root under the tree can not be soaked for a long time, soaking for a long time is easy to hurt the root.

3. Insect control and leaf protection in apricot planting.

Leaves are the nutrition factory for fruit trees, and complete and thick leaves are the guarantee of apricot fruit, which generally do not attract people's attention. Hot summer days combined with autumn drought sometimes occur, which is easy to cause red spider harm and spread, or continuous rain in late autumn. It is easy to cause fallen leaf diseases, resulting in poor flower bud differentiation, and can be sprayed in time with a mixture of carbendazim or carbendazim, tocopherol and other pesticides to prevent diseases and pests and protect leaves. In addition, spraying 0.3% urea is more beneficial to the tree.

3. Pest control

Apricot neck rot mainly occurs at the base of the trunk of apricot and is a disease caused by a fungus. The pathogen overwintered as oospores in the soil, and in spring oospores invaded the branches of apricot trees, or they could also invade directly after oospore germination.

After the apricot tree was infected with neck rot, the cortex of the diseased part became brown and rotted, the sunken part was constricted, and the diseased part had no peculiar smell. in the upper part of the diseased part, the branches sprouted late and grew weakly. If not treated in time, the leaves will wilt, dry up and even die.

Apricot neck rot is easy to occur in orchards with heavy soil viscosity, poor soil drainage or excessive irrigation of intercropping vegetables, and extensive management of weeds. If there is a wound in the trunk neck or the graft interface is lower and buried in the soil, it is also easy to be infected with the disease. If the first crop of the newly built apricot orchard is a vegetable field, the planting holes can be dug before planting and sterilized with copper sulfate. Each hole is about 10ml and 15kg. When planting, the grafting interface should be 10ml 15cm above the ground. Repair the drainage system of apricot orchard in time to ensure that there is no stagnant water in the orchard during the rainy season. After the soil is thawed in spring, immediately remove the soil from the root neck, dry the root neck, and carefully examine the root cortex, and find that the disease spot is scraped off in time, and then apply 25% Ruidui 50 times or 40% ethyl phosphor aluminum 30 times 50 times on the wound, once every 7 min and 15 days, generally 2 mi 3 times is effective. The diseased bark scraped off should be cleaned up and burned out of the garden. Before freezing the soil in winter, pile the peeled soil on the root neck to prevent freezing.
