Moisturizing and cooling method for ginkgo twig grafting

Abstract

The invention relates to a moisturizing and cooling method for ginkgo twig grafting. The moisturizing and cooling method mainly comprises the steps of scion collection, low-temperature soaking treatment, wax sealing treatment, scion preservation and full-illumination intermittent spraying management on grafted seedlings after grafting. According to the method, the pretreatment means that low-temperature soaking of scions is combined with using of plant growth powder is adopted, the scions are soaked at the low temperature, the physiological activity is reduced, the scions are in a semi-dormant state, in addition, the plant growth powder has volatility and hygroscopicity, germination of scion branch buds can be restrained, and the scion survival rate is increased. The surface of the scion is kept dry, a water locking layer is formed on the surface of the scion, water loss is reduced, the false survival phenomenon is avoided, the dormancy period of the woody plant is prolonged, and the physiological process of the scion is adjusted through the synergistic effect. The scion and ambient air humidity is effectively improved, and the scion and ambient temperature is reduced, so that the scion germination rate and the grafting survival rate are improved.

Description

technical field [0001] The invention belongs to the technical field of ginkgo twig grafting, and in particular relates to a moisturizing and cooling method for ginkgo twig grafting. Background technique [0002] Generally, it takes about half a month for a fruit tree to heal from grafting. During this half month, the scion receives very little nutrition and water from the rootstock, and almost completely relies on itself to maintain it. Ginkgo twig grafting is carried out during the growing season (generally from mid-to-late May to early September). Generally speaking, the scions used for grafting do not need to be sealed with wax. However, the scions used for grafting from mid-to-late May to June The scion is very easy to lose water due to the low degree of lignification. In addition, the high temperature in summer from July to August can easily cause the water loss of the scion, which often causes the survival rate of tender branch grafting to be low. Due to the poor degr...

Problems solved by technology

[0004] In production practice, the full-light spraying technology is widely used in the production of young shoot cuttings, because this technology can create a high-humidity and temperature-friendly rooting environment suitable for the rooting of shoots and cuttings, and can well avoid the need to achieve high-humidity and temperature. Due to the high temperature and high humidity, low light and poor ventilation brought about by measures such as canopy closure and shade, the growth of mold will affect the survival of cuttings. Up to now, there has been no full light on the young shoots and scions after grafting. Spray technology to reduce temperature and moisturize, improve the report of grafting survival rate, for this reason, we propose a method of moisturizing and reducing temperature for ginkgo twig grafting
