Rapid loquat seedling culture method

Abstract

The invention discloses a rapid loquat seedling culture method. The method comprises the following steps: selecting a high-quality wild peach tree with good two-year growth potential; cutting a section, which is 12 to 15 cm in length and contains three integrated buds, from the branch towards south in March to April of the same year to serve as a cuttage strip; after performing sterilization and rooting liquid soaking treatment, adopting the cuttage strip at two stages of container cultivation and seedling soil cultivation to perform seedling culture. The root of the cuttage strip is stimulated by a water flow impact method, so that the quick growth of the root can be promoted, the cultivation time in a culture solution is prolonged, stress resistance is enhanced and the root system of seedlings is thickened; meanwhile, the seedlings with strong growth potential can be integrally transplanted to seedling soil, the water and fertilizer management of the seedling soil is strictly controlled, the gaps of the seedling soil are increased, the water storage and water seepage capabilities of the seedling soil are improved, the utilization ratio of the fertilizer is increased, the final-period management difficulty is reduced, the seedling culture cycle is shortened, high-quality nursery stocks are obtained through uniform management, the survival rate after transplanting reaches 98.6% or above, fruit settling is easy and the economic benefit is significant.

Description

technical field [0001] The invention belongs to the technical field of planting of agricultural seedlings, and in particular relates to a method for rapidly growing loquat seedlings. Background technique [0002] Loquats bloom in autumn or early winter, and mature in early summer. The mature loquats are delicious, nutritious, and have the effects of moistening the lungs and relieving coughs. They are often planted in fertile lands in the middle and lower reaches of the Yangtze River and south of the Yangtze River in my country. They are often used for garden viewing. Most of the existing good breeding loquat varieties are grafted. It takes at least two years from the cultivation of grafted seedlings to the management after grafting. However, if the cutting seedlings are raised with biennial branches, the degree of lignification is too high and it is difficult to take root. Branch growth is not enough, and the cost of cultivation is greatly improved, but the survival rate is lo...

[0002] Loquats bloom in autumn or early winter, and mature in early summer. The mature loquats are delicious, nutritious, and have the effects of moistening the lungs and relieving coughs. They are often planted in fertile lands in the middle and lower reaches of the Yangtze River and south of the Yangtze River in my country. They are often used for garden viewing. Most of the existing good breeding loquat varieties are grafted. It takes at least two years from the cultivation of grafted seedlings to the management after grafting. However, if the cutting seedlings are raised with biennial branches, the degree of lignification is too high and it is difficult to take root. The growth of branches is insufficient, and the cost of cultivation is greatly increased, but the survival rate is low. Therefore, there is no method for raising seedlings by cutting loquat
