Populus euphratica twig cutting technique

Abstract

The invention provides a cutting seedling technique. The cutting seedling technique can avoid the situation that the survival rate of Populus euphratica twig cutting is low, can improve the cultivation environment of Populus euphratica nursery stocks by improving the treatment chemical of cutting stems and post management, and then remarkably improve the survival rate of the Populus euphratica twigs. The cultivation technique is simple in step, is low in production cost, and can improve the survival rate of the Populus euphratica nursery stocks to more than 90%.

Description

technical field [0001] The invention relates to the field of nursery stock cultivation, in particular to the populus euphratica twig cutting technology. Background technique [0002] Populus euphratica ( Populus euphratica Oliver ), also known as Populus heterophyllum, is a rare tree species in the western desert of my country, and belongs to the national first-class protected plants. Populus euphratica often grows in deserts. It is resistant to cold, drought, salt and alkali, and wind and sand. It plays an important role as a natural barrier for the development of agriculture and animal husbandry in desert areas, and is also known as the "desert guardian". [0003] The strong resistance of Populus euphratica has made it a popular tree species for afforestation in Northwest China in recent years, but it is not easy to raise seedlings of Populus euphratica. At present, two seedling methods are mainly used: seed propagation and branch cutting. Seed propagation is easy...

Problems solved by technology

[0004]The survival rate of Populus euphratica twig cuttings using conventional methods is very low, generally less than 30%. Many years of experiments conducted by major domestic scientific research institutes have failed to achieve a good result. Solve the rooting problem of Populus euphratica
