Rapid Prototyping of Fruit Bonsai (I)

The exquisite vegetarian pot is the most suitable for the container, which requires good water seepage and air permeability to ensure the oxygen requirements of root growth and prevent the rotting root caused by stagnant water in the container. Generally, it is mainly round, so that the root system can spread evenly around.

Grafting

Split grafting selects the branch group (with 2 to 4 branches) which is thinned by winter pruning as scion. Rootstocks can be grafted without survival or other sturdy dwarfing rootstocks. The grafting was carried out one month before the sap flow. Split in the center of the smooth cut of the rootstock, 3 to 4 cm deep, cut the scion (the lower sides are obliquely cut to a smooth plane, 2 to 3 cm long), insert the split of the rootstock at the cambium, and fasten it tightly with plastic tape and rope from bottom to top. Pot or ground for a year. When planting, the soil should be buried through the interface to keep warm, so that it can not move.

The root connection takes place before and after the Qingming Festival. To choose strong, stress-resistant root rootstock, scion with old thick pile section or well-shaped branch group. It can be connected with 2 to 4 rootstocks by inserting skin and tongue.

Soil fertilizer and water management

The nutrient soil was prepared by pot soil according to the different needs of fruit trees for soil nutrients. The culture soil should be disinfected before use, such as baking disinfection or drug (1.5% formalin) disinfection, etc.

The application of base fertilizer should be based on organic fertilizer, reasonably mixed with chemical fertilizer, and mixed with rotten organic fertilizer when it is put on the basin.

After topdressing, one quick-acting nitrogen fertilizer was applied before flowering, with an appropriate amount of phosphate fertilizer, and about 1 kg of fertilizer was irrigated per plant; after Xiehua, 0.3% potassium dihydrogen phosphate plus 0.3% urea could be used, spraying once every 15 days, 3 to 4 times; one month before fruit harvest, 60 grams of potassium dihydrogen phosphate was applied in each pot.

Watering should be thoroughly watered once after each topdressing; in flowering and young fruit stage, it is necessary to prevent physiological flower and fruit drop caused by too wet; in flower bud differentiation stage and fruit ripening stage, water should not be too much, but should be slightly dry; in fruit expansion period, basin soil should be neither too dry nor too wet. Watering should be strictly controlled during the dormant period, so that the basin soil is only dry.

As the nutrients in the basin soil are washed away in frequent watering, the basin should be emptied in time every 2 years to replace the new nutrient soil.
