Cultivation method for container grafted seedlings of fructus phyllanthi

Abstract

The invention relates to a cultivation method for container grafted seedlings of fructus phyllanthi, belonging to the technical field of agriculture. The cultivation method comprises the following steps: selection of containers for seedling raising, preparation of a substrate, bagging and placement of the containers for seedling raising, erection of a sunshade awning, seed sprouting and sowing, erection of a small plastic film shed, management and protection of seedlings, rootstock selection and treatment, scion collection, grafting as well as management and protection of grafted seedlings. Testing results indicate that compared with other fructus phyllanthi grafted seedling cultivation technologies, the cultivation method disclosed by the invention has the advantages of simple and convenient operation, good and stable seedling quality, low seedling culture cost, good afforestation effect, cleanliness, environmental friendliness and the like, effectively solves the production problems that the survival rate is low in bare-rooted forestation of fructus phyllanthi, the grafted survival rate is low when the fructus phyllanthi seedlings are grafted after being put into the containers for seedling raising, and the afforestation survival rate is low because of serious root system damage when container grafted seedlings cultivated according to a traditional technology are out of a nursery garden, and has a broad application prospect in the production.

Description

technical field [0001] The invention belongs to the field of agriculture—forestry—breeding of forest tree seedlings—container seedlings—cultivation of grafted seedlings, and specifically relates to a cultivation method of Yunnan olive container grafted seedlings. Background technique [0002] Yunnan olive has strong adaptability to the ecological environment of tropical and subtropical dry-hot valley regions, especially has obvious functions of water retention and soil consolidation. It is one of the pioneer tree species for afforestation of barren hills in this area. In 2001, we began to carry out the selection of tree species suitable for afforestation and the selection of improved varieties in the dry-hot valley of the Nujiang River Valley, where ecological restoration is difficult. After more than 10 years of experimental cultivation, we successfully selected the improved variety of Yunnan olives in 2013—Gaoligongshan Nuodian olive (improved variety No. cloud R-SC-PE-069...

AI Technical Summary

Problems solved by technology

However, due to the high labor intensity and time-consuming work of transplanting and bagging, the cost is high, the mortality rate of transplantation is high, and the survival rate of transplantation is only 42.3%, which leads to a sharp increase in the cost of seedling cultivation and it is difficult to achieve large-scale application in production.

[0007] In view of the technical defects of Yunnan olive seedlings mentioned above and the small size of Yunnan olive seeds and the inability to realize the cultivation of grafted seedlings, it is fully demonstrated that there are few lateral roots of Yunnan olive seedlings, the main root of seedlings grows fast downward, and the grafted seedlings of 2-year-old root age are too large. On the basis of characteristics such as large size, inability to cultivate grafted seedlings in buds and anvils, and actual production, the applicant carried out research on the cultivation technology of grafted seedlings of Yunnan olive varieties
