Problems solved by technology

[0003] Over the years, Guangxi has never solved the problem of mulberry seedling cultivation. As a kind of fruit, mulberries are more and more popular among consumers. At the same time, mulberry trees are also seedlings needed for planting mulberry trees. The cost is high, and the mulberry seedlings are easy to lose water, resulting in a low survival rate after planting. At the same time, some quarantine mulberry pests and diseases are brought in. In order to get rid of this passive situation, we are now vigorously developing the cultivation of grafted seedlings. 5 million plants, according to statistics, the survival rate of some plots and some planting rows is as high as 90% or more, and the survival rate of some planting is less than 30%. In the spring of 2010, self-cultivation and self-grafting were adopted. 5000 plants, the average survival rate of planting is 65%

Embodiment 1

[0019] A method for improving the survival rate of mulberry seedling grafting, comprising the following steps:

[0020] (1) select rootstock: select annual, ungrafted, adapt to local growth, and the mulberry seedlings whose rhizome is 0.5~0.7cm are used as rootstock;

[0021] (2) Select the scion: choose a tree bar with full buds, fullness, no side branches, and appropriate thickness on a 1-year-old healthy and healthy mulberry tree; cut off the scion 15 days before grafting and place it in an airtight, ventilated, and cool place 1. In the heat preservation and moisturizing room, first spread 10cm of tidal sand on the floor of the room, spread the scion 5-10cm thick, fill in 5cm thick tidal sand, then spread the scion 5-10cm thick and cover it circularly, cover it with plastic film and close the doors and windows , the temperature is maintained at 5-10°C, and the relative humidity is 75%, so as to ensure that the scion does not dry up, germinates in advance, and does not go mo...

Embodiment 2

[0024] A method for improving the survival rate of mulberry seedling grafting, comprising the following steps:

[0025] (1) select rootstock: select annual, ungrafted, adapt to local growth, and the mulberry seedlings whose rhizome is 0.5~0.7cm are used as rootstock;

[0026] (2) Select the scion: choose a tree bar with full buds, fullness, no side branches, and appropriate thickness on a 1-year-old healthy and healthy mulberry tree; cut off the scion 15 days before grafting and place it in an airtight, ventilated, and cool place 1. In the heat preservation and moisturizing room, first spread 10cm of tidal sand on the floor of the room, spread the scion 5-10cm thick, fill in 5cm thick tidal sand, then spread the scion 5-10cm thick and cover it circularly, cover it with plastic film and close the doors and windows , the temperature is maintained at 5-10°C, and the relative humidity is 75%, so as to ensure that the scion is not dry, does not germinate in advance, and does not go...

Embodiment 3

[0029] A method for improving the survival rate of mulberry seedling grafting, comprising the following steps:

[0030] (1) select rootstock: select annual, ungrafted, adapt to local growth, and the mulberry seedlings whose rhizome is 0.5~0.7cm are used as rootstock;

[0031] (2) Select the scion: choose a tree bar with full buds, fullness, no side branches, and appropriate thickness on a 1-year-old healthy and healthy mulberry tree; cut off the scion 15 days before grafting and place it in an airtight, ventilated, and cool place 1.

Abstract

The invention relates to a method for increasing the grafting survival rate of mulberry saplings, and belongs to the field of agricultural planting. The method for increasing the grafting survival rate of the mulberry saplings includes steps of (1), selecting one-year mulberry seedlings to be used as rootstocks; (2), selecting substantial and intact tree branches to be used as scions, and wettingthe scions by means of clear water spraying on the night before the scions are grafted so as to allow the scions to sufficiently absorb the water; (3), grafting the scions to the rootstocks by the aidof bag grafting processes, simultaneously smearing grafting healing agents on the peripheries of grafting openings, and then binding the grafting openings by the aid of plastic films. The one-year mulberry seedlings which are selected to be used as the rootstocks at the step (1) are not grafted, can adaptively locally grow and have rhizomes with the sizes of 0.5-0.7 cm. The tree branches which are selected to be used as the scions at the step (2) are selected from one-year robust improved-variety mulberry without diseases or pests, have plump buds and appropriate thicknesses and are free of lateral branches. The method which is a grafting method has the advantages that the survival rate of grafted seedlings of the mulberry saplings can be obviously increased by the aid of the method and can reach 95-98%, the recovery periods can be effectively shortened, nursery stock can be prevented from withering, and growth of the mulberry saplings can be promoted.

Description

【Technical field】 [0001] The invention relates to the field of agricultural planting, in particular to a method for improving the survival rate of grafted mulberry seedlings. 【Background technique】 [0002] Grafting mulberry seedlings has the characteristics of a large number of seedlings per unit area and strong growth of mulberry seedlings after survival. It is a rapid seedling raising method and approach to meet the needs of large-scale planting. At present, the national project of "moving mulberries from east to west" is being implemented steadily. In the next few years, this project alone will require about 500 million mulberry seedlings every year. Therefore, identifying the factors that affect the survival of mulberry grafting and raising seedlings, and taking effective countermeasures will not only help improve the efficiency of seedling raising per unit area, but also help meet the needs of the national "Moving Mulberry from East to West" project, and steadily promo...
