Preparation method for compound preparation for promoting grafting survival of elms and zelkova schneideriana

Abstract

The inventin belongs to the field of agriculture and forestry and provides a preparation method for a compound preparation for promoting grafting survival of elms and the zelkova schneideriana. The elms serve as scions, the zelkova schneideriana serves as rootstocks, and the survival rate in medium-degree salt and alkali areas with the dry and cold climate is quite low. The grafting survival rate of the elms and the zelkova schneideriana can be increased through the preparation method. The preparation method is characterzed in that cucumber juice, carrot juice, malonic acid and ethylene glycol monoethyl ether acetate are mixed, and the compound preparation comprises, by weight, 40 parts of cucumber juice, 65 parts of carrot juice, 13 parts of malonic acid and 3 parts of ethylene glycol monoethyl ether acetate.

Description

technical field [0001] The compound preparation for grafting and promoting the activity of elm and beech belongs to the field of agriculture and forestry. Background technique [0002] Elm tree, Latin scientific name Ulmus pumila L., positive tree species, light-loving, drought-resistant, cold-resistant, barren-resistant, regardless of soil, strong adaptability. Well-developed root system, strong wind resistance and soil retention. Strong germination and resistant to pruning. Fast growth and long life. It can tolerate dry and cold climates and moderate salinity, but it is not resistant to water and humidity (it can withstand waterlogging in rainy seasons). It is anti-pollution and has strong ability to retain dust on the leaf surface. [0003] Beech, whose scientific name is Zelkova serrata (Thunb.) Makinoz, is an arbor tree species belonging to the genus Beech in the family Ulmaceae, and it is a national second-class key protected plant. It is widely distri...

Problems solved by technology

[0005] With zelkova as scion and elm as rootstock, in a suitable environment, the survival rate of grafting is very high, but in dry and cold climate with moderate saline-alkali area, the survival rate is very low, even if the operation is careful (during grafting: scion cut surface Smooth and flat, the cambium of the scion and rootstock are aligned, and the binding is moderate), and the survival rate is only 10%.
