Cutting method for lavenders

Abstract

The invention provides a cutting method for lavenders. The cutting method includes the following steps that first, grass-charcoal earth, vermiculite and countryside soil are evenly mixed to serve as a cutting medium, and then the cutting medium is loaded into nutrition cups respectively, watered thoroughly through 100-fold carbendazim, disinfected and sterilized; cutting branches are selected and treated; cutting is performed; seedlings are hardened; seedling emerging is performed; when the cutting seedlings grow to have three or more lateral branches, the seedlings can emerge to be transplanted to a field after root systems huddle. Compared with the prior art, the temperature of the cutting environment is controlled to be about 25 DEG C, humidity is controlled to be above 75%, and therefore the survival rate of cutting reaches about 90% for the lavenders. Intensive management is adopted, so that management is convenient; the cutting method is not affected by weather and is high in automatic control; the occupied area is small; the age of the seedlings is shortened, and seedling-cultivating time is shortened.

Description

technical field [0001] The invention relates to the field of lavender planting, in particular to a lavender cutting method. Background technique [0002] The existing lavender planting methods generally include: [0003] Soil preparation: choose sandy land with good drainage and deep soil, and plow the land 25-27cm deep; before plowing the land, apply 3000-4000kg of farmyard manure, 25-30kg of superphosphate, and 10-15kg of urea per mu; spray 100 times liquid Carbendazim, and covered with black plastic film; [0004] Select cuttings: the temperature is below 0°C, during the dormant period of lavender, select two-year-old and three-year-old robust lavender with the characteristics of this product, and cut 10-15cm long branches; cut the bottom of the branches obliquely at 40-50°, use 0.1 % Potassium permanganate soaked for 30min, then soaked in 500ppm naphthaleneacetic acid for 2h, and cut off the upper 2-5cm twigs; [0005] Planting: cutting according to the row spacing of...

AI Technical Summary

Problems solved by technology

[0008] However, this planting method is greatly affected by the seasonal weather during the production process, and the temperature and humidity are uncontrollable, which leads to a very low survival rate of lavender cuttings. Generally, the survival rate of cuttings is only 40% to 60%.

[0009] Due to various reasons in history and insufficient introduction of geographical location and science and technology, the cultivation of lavender in Chengdu still has low survival rate and high production cost.

The planting effect of lavender is easily affected by the regional soil environment. Because lavender is not resistant to waterlogging, it will wither and wither prematurely if it is slightly improper, and there are unreasonable technical deficiencies in the pesticides and fertilizers used in the planting process. Calcium chloride and calcium phosphate are often used in the compound fertilizer applied in the prior art, which affects the growth of lavender, resulting in the low quality of the extracted essential oil and failing to achieve the actual effect
