Description
Technical Field
The invention relates to the technical field of seedling propagation, in particular to a method for grafting red gem pomelo.
Background
The green pomelo is also called as emerald pomelo, which is originally near Mangu of Thailand, has a low-lying land, is in a short spherical shape, has pink pulp, small fruit center, softer and juicy pulp compared with white pomelo, has high sugar degree and low sour taste, and is also called as honey pomelo. The green pomelo has crystal, crisp and tender fruit meat, thin skin and thick meat, the edible rate reaches more than 80 percent, the juice is rich and seedless, the sweetness is moderate, and the green pomelo is fragrant and tasty when being eaten. The green pomelo fruit can be stored for 2-3 months at normal temperature after being harvested, does not change color, flavor or rot, and still can keep excellent quality and flavor, and the mature fruit can be hung on a tree for months without picking, can not fall off, and has better quality, so the green pomelo fruit can be named as a natural can. The weight of a single fruit is about 2.5 jin, and the big weight can reach 5-6 jin. Each plant of the 2-year-old trees can bear 30-50 fruits by field planting, and the yield per mu can reach 3000 plus 4000 jin; each plant of the 3-year-old tree can bear 50-80 fruits, and the yield per mu can reach 7000-9000 jin; each plant of the 5-year-old tree can bear 100 plus 200 fruits, and the yield per mu can reach ten thousand jin; after entering the high-yield period, each plant can bear more than 300 fruits, the yield per mu can reach two thousand jin, and the yield is extremely high compared with other varieties. The traditional shaddock variety in China generally can be on the market after 10 months and 1 day. The crystal green pomelos begin to appear on the market in the last 6 months of each year, and are harvested to the end of 8 months, so that the crystal green pomelos and the traditional pomelos form a natural out-of-season. The price is competitive. Since the product is put on the market, the selling price per jin is kept above 3 yuan. The market advantage is very outstanding.
The green pomelo is nutritious. Fruit juice soluble solid 12-25%. Every 100mL of fruit juice contains 7-15g of sugar, 0.3-1.5g of acid and 40-250mg of vitamin C; in addition, the beverage is rich in vitamin B1, vitamin B2, vitamin P, carotene, calcium, phosphorus, iron, magnesium, zinc, potassium, sodium and the like. The juice cells of the oil cell core pulp of the mature fruit peel contain higher alcohols, aldehydes, ketones, volatile organic acids, alkenes and the like, and send out attractive fragrance until the juice cells are full of faint fragrance and the juice cells are fragrant and full of breath when being eaten. The leaves, flowers, fruits and peels of the green pomelos can be extracted to obtain essential oil, the pulp (juice cells) can be prepared into natural beverages such as pomelo juice, pomelo beer and the like, and the pomelo peel can be used as a material and a raw material for processing preserved fruits and can preparation, so that the application value is extremely high.
At present, the propagation of green pomelos mainly comprises seedling propagation and grafting propagation. The seedling propagation method is characterized in that seeds of large and mature fruits are taken, drill sowing or broadcast sowing is adopted, water is fully sprayed after sowing, soil is kept moist, when seedlings grow to 10cm high, the seedlings are planted in beds or transplanted into nutrition bags, and field planting can be carried out after 1 year of cultivation. The grafting propagation can ensure that the offspring keeps the excellent characters of the mother tree, at present, the seedling obtained by sowing is mainly adopted as the stock, and the grafting with the scion is carried out after the seedling grows to a certain height, so the propagation speed of the method is low, and the cost is high.
When a grafting propagation mode is adopted, the stock and the scion are easy to generate absciss layers, and the main reason is that the stock and the scion are incompatible and can not grow callus, or the growing callus can not be communicated with the conduction tissue, or the communicating conduction tissue can not be communicated with other substances for growing other substances because a conduit or a sieve tube is blocked and can not carry out nutrition exchange. Secondly, the grafting method has certain influence on the grafting method, for example, the citrus grafting in spring is not mainly performed by cutting grafting, but is performed by selecting abdominal grafting wrongly. Due to excessive abdominal grafting, the rootstock trees are disadvantaged in competing for nutrients after bud survival, and therefore the seedlings die.
There are many varieties of Thai green pomelos, such as Thai ruby green pomelos, Thai emerald green pomelos, Thai honey pomelos, Thai kaya green pomelos, and the like, and the varieties are various. The red pomelo has fresh, sweet and delicious taste, low annual output and relatively expensive market price compared with other varieties of pomelo.
The researchers of the invention find that the red gem green pomelo is easy to have a separation layer during grafting, and the grafted seedling is not good enough in growth and fruit bearing conditions after survival, mainly because the compatibility of the stock and the scion is not enough, the activity of the stock or the scion is low, the callus growth is slow after grafting, and the subsequent planting, growth, fruit bearing, product quality and the like are greatly influenced.
Therefore, the grafting method for reducing abscission is adopted to breed the ruby green pomelos, the survival rate and the growth quality of the ruby green pomelos seedlings are improved, and the planting economic benefit is improved.
