Grape summer breeding method
Grape seedlings for summer cuttings can be harvested in the fall of the year, which is an effective method to shorten the nursery cycle. Many years of practice have proved that this method has the advantages of short time for seedlings, high survival rate, reduced winter storage process and investment, good seedling quality, strong growth, and good economic benefits. Its specific technology is as follows: First, cutting time It can be carried out from June to August, preferably in summer, when the shoots grow to 5-10 knots, semi-lignified with a certain degree of hardness and maturity with the scissors. Second, the preparation of the bed Seed beds should be selected for light, irrigation and irrigation, and soil loose and fertile. The seedlings are ploughed and leveled to form a 1-1.2 meter wide slotting machine (usually inserted in 3-4 rows with 6-8 cm spacing). At the same time, stand and branches are prepared for shading. In order to improve the survival rate of summer insertion, 0.005%-0.007% indole acetic acid can be used to soak the cutting base for 6-8 hours before cutting, or with 0.1%-0.3% indole acetic acid for 5 seconds, or with rooting powder. Third, the cutting operation 1. The cuttings should be selected from vines that have been lignified and their buds are yellow-brown, cut into small pieces 20-25 cm long (with 3-5 knots), leaving 1 leaf at the cutting tip, and the other leaves are cut off together with the petioles. Cut from the outside of the shoot to the horse's ear and insert the seedbed immediately after cutting. After the cuttings, the soil is compacted, and the water is poured and a shade shed is erected. The shed is 0.8-1 meters high. The shed has the same width and width, and the shade degree is 60%-70%. After the insertion, the bed should be kept moist and not waterlogged. After 15-20 days of insertion, the cuttings sprout, and new vines can be removed to gradually remove the shed. 2. It is worth noting that because the cuts are easy to lose water, they should be inserted with the scissors. After sprouting, a small amount of topdressing should be carried out in order to ensure the quality of seedlings in the fall. Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent. WS-23,flavor,Menthol,WS-5,Koolada,WS-12 Xi'an Double H Health Technology Co., Ltd , https://www.xahnhcj.com
