Hawthorn is the fruit of drug use either species endemic to China. Hawthorn is a wide variety of fresh and processed fruit are on the market bullish. Hawthorn in the mountains, plains, hills, sandy wasteland, acidic or alkaline soil can be cultivated. Hawthorn production in recent years, low yields and unstable yield cultivation techniques hawthorn are summarized below. Fertilizer and water management 1.1 soil management soil deep plowing ripening stimulation technology measures the deep plowing ripening, can improve the soil, increase soil permeability, promoting the growth of the tree. 1.2 base manure fertilization, after failing to timely base manure, to supplement the nutrition of the tree, fertilizer to organic fertilizer, organic fertilizer 3000 - 4000 kg per mu ditching added urea 20 kg, 50 kg superphosphate , plant ash 500 kg. Dressing, generally one year to recover three times a fertilizer, in mid-March, when the sap starts flowing, plant topdressing urea 0.50 - 1 kg to replenish the nutrients needed for growth of the tree to lay the foundation to improve fruit. Flower of 0.50 kg of urea per plant facilities to improve fruit. Per plant facilities prior to the end of July flower bud differentiation of 0.50 kg of urea, superphosphate 1.50 kg, ash 5 kg to promote fruit growth and improve fruit quality. 1.3 watering generally 1 year 4 times pouring water spring irrigation conditions in the top dressing after pouring water to facilitate the absorption and utilization of fertilizers. Combine dressing watering after flowering to improve fruit. Pouring water after the wheat harvest, to promote the rapid growth of the flower bud differentiation and fruit. Poured freezing water in winter time pouring freezing water, in order to facilitate tree winter safely. 2 pruning 2.1 winter pruning 2.1.1 to prevent within stare bare, are closed due to the the Hawthorn peripheral easy branching, often peripheral, bore sprig growth weak, dead branches has increased every year, at all levels of the large branches in the lower part of gradually naked bald. Thinning and shrinking, as the principle of combining prevent bore bare measures should be used to transform and Rejuvenation, the backbone branches whorled and peripheral sparse to dense large branches and competitive branches, leggy branches, worms branches shrink scissors weak the main the collateral, choose to stay to the appropriate parts of the bud small update, cultivate robust Zhizu. Transformation of the weak branches heavy cut rejuvenation and engraved hurt the the bare parts buds on branches gain. 2.1.2 little stub Hawthorn entered the final period, where a substantial growth shoots below the terminal bud and its 1 - 4 buds, flower buds can be differentiated into, so should be used sparingly in the hawthorn trim short cut method, in order to protect the flower buds. The 2.1.3 complex potential haw the result of years of continuous results, leading to the drooping branches waning growth potential backbone sticks coke tip, decline. To update branches in a timely manner to restore tree vigor. For years of continuous results of sticks or other lengthy branches, drooping branches, coke Kozue perennial leggy branches retracted to the rear of the strong
