Description

Mango grafting method
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of fruit planting, in particular to a mango grafting method.
[ background of the invention ]
Mangoes are called "tropical fruit kings" and are distributed in almost all tropical and subtropical countries and regions. At present, mango planting places in China are mainly concentrated in regions such as Hainan, Sichuan, Taiwan, Guangxi, Yunnan and the like. Since the market economy is opened, China breeds a batch of excellent new mango varieties, wherein more than 100 varieties of cultivation varieties comprise early, middle and late maturing varieties, and the breeding of the new varieties plays a great promoting role in the development of the mangoes in China. Mango is exported to other countries, and although the consumption of mango in China is not high, the population base of China is large and the market demand potential is huge.
The grafting is one of asexual propagation techniques, can maintain the excellent quality of the female parent, is not easy to have variation, dwarfs the tree vigor, is convenient for picking, advances the bearing age and improves the yield of the fruit. The conventional mango grafting method generally has the problems of low grafting survival rate and long budding time, and the market demand for high-quality grafted seedlings is difficult to meet.
[ summary of the invention ]
The invention aims to: aiming at the problems, the mango grafting method is provided. According to the mango grafting method, the grafting nutrient solution is reasonably applied, and other grafting factors are combined, so that the mango grafting survival rate is effectively improved, and the budding time of the grafted seedling is shortened.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a mango grafting method comprises the following steps:
(1) treating the rootstock: selecting a seedling of 2-3 years, cutting the top of the seedling 70-80cm away from the ground, cutting a cut 2-2.5cm in length and 5-6cm in depth below the cut, and spraying a grafting nutrient solution to the cut and the cut to obtain a stock for later use;
(2) scion treatment: selecting 1-2 year-old branches with more leaf buds and plump bud eyes, obliquely cutting the branches at the positions 1-1.5cm below the buds of the branches, cutting 1.2-1.8cm long cortex on the reverse side, and then cutting the branches with 2-3 buds to obtain scions;
(3) grafting: inserting the lower end of the scion into the cut of the stock, attaching the scion to the cortex of the stock, and then fastening the scion and the cortex of the stock by using a plastic film tape to obtain a grafted seedling;
(4) and (3) grafting management: in 15d of grafting, spraying water for 1 time/day, and removing the foot buds in time; after 15 days, applying fertilizer regularly, and spraying disease-preventing liquid when the new buds germinate;
the grafting nutrient solution comprises the following raw material components in parts by weight: 4-8 parts of gibberellin, 2-5 parts of kinetin, 3-8 parts of enteromorpha degradation extract, 1-5 parts of alginic acid, 2-5 parts of chitosan, 0.2-0.5 part of iodine and 0.3-0.5 part of sorbitol;
the disease prevention liquid comprises the following raw material components in parts by weight: 2-5 parts of cogongrass rhizome, 2-5 parts of inula flower, 3-8 parts of fructus kochiae, 1-5 parts of tripterygium wilfordii and 1-3 parts of rhizoma arisaematis.
Further, the grafting nutrient solution comprises the following raw material components in parts by weight: 6 parts of gibberellin, 4 parts of kinetin, 5 parts of enteromorpha degradation extract, 3 parts of alginic acid, 3 parts of chitosan, 0.4 part of iodine and 0.4 part of sorbitol.
Further, the grafting nutrient solution is mainly prepared by the following method: weighing the raw material components in parts by weight; and (3) mixing and stirring the weighed raw material components uniformly, and adding purified water to adjust the mass concentration of the gibberellin to be 60-80mg/L to obtain the grafting nutrient solution.
Further, the disease prevention liquid comprises the following raw material components in parts by weight: 4 parts of cogongrass rhizome, 3 parts of inula flower, 5 parts of broom cypress fruit, 3 parts of tripterygium wilfordii and 2 parts of rhizoma arisaematis.
Further, the disease prevention liquid is mainly prepared by the following method: weighing the following raw material components in parts by weight; mixing and crushing the weighed raw materials, adding ethanol, treating for 40-60min by adopting ultrasonic waves, and filtering to obtain the disease preventing liquid.
Further, the cross section diameters of the rootstock and the scion are 1.5-2.5 cm.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
the mango grafting method effectively promotes the extension, division and differentiation of the scion and cambium cells after grafting by spraying the special grafting nutrient solution to the scion and the grafting opening of the stock, effectively promotes the healing of the scion and the grafting opening, and is beneficial to the scion to absorb water and nutrients from the stock, thereby improving the grafting survival rate and the sprouting speed. Furthermore, in the process of grafted seedling management, a special disease-preventing liquid is adopted to spray new buds, the disease-preventing liquid has a killing rate of more than 89.7% for the noctuids with high incidence of mango grafted seedlings, which is 18.9-25.7% higher than that of a single component in the disease-preventing liquid, meanwhile, the disease-preventing liquid has an inhibition rate of more than 84.6% for mango anthracnose pathogens, which is 15.8-19.9% higher than that of a single component in the disease-preventing liquid, so that the incidence of mango grafted seedlings is effectively reduced, the robust growth of the grafted seedlings is promoted, the transplanting survival rate of the grafted seedlings reaches more than 91.2%, and compared with the grafted seedlings obtained by the existing disease-preventing liquid management, the transplanting survival rate of the grafted seedlings is improved by 12.3-15.7%.
