How many years does the Hawthorn tree bear fruit? What are the main points of planting techniques?

There are many varieties of Hawthorn, fresh food and processed fruits are sold well in the market, with medicinal and edible value. At present, Hawthorn is also widely planted, because Hawthorn has strong adaptability and can be cultivated in mountains, plains, hills, sandy wasteland, acidic or alkaline soil. How many years does the Hawthorn tree bear fruit? What are the main points of planting techniques?

First, Hawthorn general how many years result?

Hawthorn trees generally bear fruit for 3 ~ 4 years, and enter the full fruit period before and after 10 years. The yield of each tree can reach 100 kg at the age of 50-70 years, and the yield of big trees is as high as 300 kg. Hawthorn has strong adaptability, likes cool and humid environment, namely cold-resistant and high-temperature-resistant, and can grow in the range of-36-43 ℃.

2. Key points of planting techniques of Hawthorn tree

1. Applying base fertilizer in autumn

It is best to do it in time after fruit picking in late autumn, which can promote the absorption and accumulation of nutrients and is beneficial to the differentiation of flower buds. The application of base fertilizer should be based on organic fertilizer, combined with a certain amount of chemical fertilizer, which should be properly mixed with organic fertilizer or soil before being applied into the ditch to avoid root burning.

Hawthorn young trees apply 40-80 kg of rotten barnyard manure per year, 0.3-0.5 kg of chemical fertilizer (pure nitrogen) throughout the year, 70 kg of organic fertilizer per tree in full fruit period, 1.5-2 kg of urea (or 2-3 kg of ammonium bicarbonate) and 1 kg of potassium sulfate.

2. Timely ring cutting

Ring cutting or girdling of young Hawthorn trees can temporarily intercept the organic nutrients produced by leaves for centralized supply, flowering and fruit setting or flower bud formation. From late May to late June, a blunt blade was used to cut the smooth part of the trunk to the depth of xylem control and flower promotion.

3. Topdressing at flowering and fruiting stage

Pre-anthesis topdressing is mainly nitrogen fertilizer and phosphate fertilizer, which is generally about 35% of the annual application rate; topdressing in the young fruit stage is mainly the early differentiation of flower buds to improve nutritional conditions; potassium fertilizer is the main topdressing in the fruit expansion stage, which mainly promotes the growth of fruit and increases the carbohydrate content of Hawthorn. Every year in the flower bud differentiation stage and flower bud stage, Bond Shouhua Lizhuang organic water-soluble fertilizer is sprayed to promote the healthy growth of flower buds and improve the fruit setting rate. In young fruit stage and fruit expansion stage, Bond first fruit Lizhuang organic water soluble fertilizer can be sprayed to promote fruit uniformity, improve sweetness, smooth color and yield.

4. Pruning should be careful.

The pruning of Hawthorn tree should be mainly in winter, rejuvenation and rejuvenation should be carried out, whorled backbone branches and peripheral dense branches, competitive branches, long branches, disease and insect branches, and weak main and lateral branches should be removed, and buds in appropriate parts should be selected for small renewal. cultivate a robust branch group. The methods of heavy cutting and rejuvenation of weak branches and engraving and increasing branches on the buds of bald parts were modified. The wound during pruning is closed and protected by "callus anticorrosive film" to prevent dry crack and disease and insect pests.

5. Drought and waterlogging drainage

Hawthorn trees are generally watered four times a year, and the amount of irrigation varies according to tree age, tree potential and soil. generally, each irrigation should reach 40-60 cm of soil moisture in the crown projection area. Under the condition of irrigation in spring, water should be irrigated once after topdressing in order to promote the absorption and utilization of fertilizer. From after falling flower to before physiological falling fruit, combined with topdressing and watering can reduce the fruit drop after flowering and benefit the appearance of the first fruit growth peak, accelerate the fruit expansion, and thus increase the fruit setting rate.

Watering before the last peak of Hawthorn fruit growth in August had an obvious effect on accelerating fruit expansion. Pour enough frozen water in time in winter to help the trees survive the winter safely. Hawthorn orchards with low-lying and waterlogged soil should be dug to drain waterlogging and remove stagnant water in time.

The measure is to cultivate soil on a tree plate to prevent stagnant water. Timely loosen the plane, enhance soil ventilation, promote water evaporation, and reduce soil water content. 6. Sterilization, disinfection and prevention of diseases and pests

In the winter dormancy period and spring germination before the use of garden medicine to protect flower buds, disinfection and sterilization, heat preservation and anti-freezing. Control red spider and peach borer from early May to early June. In mid-June, late July, early August, we pay attention to the control of peach heart borer, ring disease and so on. For Hawthorn orchards with severe powdery mildew, spray once before germination, spray 50% carbendazim wettable powder once in flower bud stage and June into 50% methyl thiophanate wettable powder.
