Description
Technical Field
The invention relates to the technical field of agricultural planting, in particular to a method for grafting and seedling raising passion fruit with double cut roots.
Background
Passion fruit, also known as eggfruit, is a herbaceous vine of the passionflower genus of the passionflower family, and can be eaten raw or used as vegetable or feed. It has exciting and strengthening effects when used as a medicine. The pulp is juicy, and can be added with calcium bicarbonate and sugar to make aromatic and delicious beverage, or added into other beverage to improve quality of beverage. The seed can be used for oil extraction, and can be used for preparing edible soap, oil paint, etc. The flower is big and beautiful, has no fragrance, and can be used as a garden ornamental plant. In other areas except China, the eggplants are called as "the king of fruit juice", "the money tree", and the like; the eggfruit contains 17 amino acids, is rich in 165 substances such as protein, fat, sugar, vitamin, calcium, phosphorus, iron, potassium, SOD enzyme, super fiber and the like which are beneficial to human bodies, is called as the king of VC (vitamin) in fruits, and has unique taste, natural purity, strong sweetness and sweetness, and is sour and sweet; has effects in promoting salivation, quenching thirst, refreshing brain, relieving constipation, and preventing carcinoma of large intestine; tonifying kidney, strengthening body constitution, removing toxic substance, and caring skin; effects of relieving alcoholism, protecting liver, and relieving fatigue; can reduce hypertension, hyperglycemia, and cholesterol; it can be used for treating oral ulcer, periodontitis, pharyngolaryngitis, colitis, and gastrointestinal diseases; can regulate blood sugar, prevent diabetes, relieve osteoporosis, strengthen skeleton, improve immunity, and prevent diseases.
In view of the abundant edible and medicinal values of the passion fruit, the application range is very wide, and the market demand is very large. At present, Chinese passion fruit growing areas are mainly concentrated in southern provinces, the yield is seriously insufficient, and the market is in a state of short supply and short demand for a long time. In the traditional grafting method, the root system of the passion fruit mainly grows downwards. However, as the passion fruit is a shallow root crop, the plant mainly absorbs nutrition in a soil layer of 0-20cm, and the popularization rate of the drip irrigation fertilization among common farmers in China is still not high, the fertilization is often close to the ground surface. The root system of the passion fruit is concentrated at the lower part, lateral roots are not developed, so that the absorption of plants to nutrition is not facilitated, the utilization rate of fertilizer is low, the planting cost is increased, and the yield benefit is influenced, so that a method capable of solving the problems is urgently needed.

Further, in the step (1), during sowing, the stock seeds are firstly put into 0.1% carbendazim solution for soaking and disinfection for 30min, then are soaked for a period of time by using nutrient solution, and are taken out when the stock seeds swell and sprout quickly, and are sowed into a seedling tray; the seedling culture tray is a foldable plastic square-corner seedling culture tray, supports are arranged on four legs, and the tray is not in contact with ground soil; the size of the seedling cup is 9cm multiplied by 9 cm.
Further, the planting substrates are all peat soil: perlite 9: 1, the watering is performed by deep well water or tap water.
Further, in the step (2), the fertilizer is an organic fertilizer solution fermented by crops, the solution is rich in organic matters, nitrogen, phosphorus and potassium, and the culture medium is a solid culture medium.
Further, the culture medium contains sugar residues, shrimp shell powder, diatom ooze and perlite, and the ratio of the components in the culture medium is 10:2:2: 0.1.
Further, in the step (2), the scion is cut from the nontoxic tender branch which grows vigorously on the mature plant and contains a stem segment of a single axillary bud or lateral bud with the length of 5-8 cm.
Further, in the step (3), the cleft grafting method is to cut a 1 cm-deep cut from the middle of the upper end of the stock, cut the lower end of the scion into a V shape, and insert the V-shaped cut into the cut of the stock to enable the two to be tightly connected.
Further, the diameter of the rootstock is 0.3-0.4 cm.
Further, the suitable temperature and humidity are 25-30 ℃, and the humidity is 75-90%.
