Kiwifruit is an economic fruit tree with rich nutrition, high economic value and broad market prospects. Traditional methods of grafting and seedling generally require two years of production. In order to shorten the nursery cycle and reduce the cost of raising seedlings, the author started from 1986. The experiment succeeded in using a small arch shed to sow seedlings from the planting to the nursery only one year. The technology is introduced as follows:

First, seed layered sand in late December to early January, first soak the seeds with cold water, make it fully absorb water. Use 5 to 10 times of clean wet sand to mix (humidity is 5% to 10% of water content). Place the mixed sand seeds in a flower pot or wooden box. Dig the pots or wooden boxes in the shade. Put in, cover with earth about 40 centimeters thick and make the mound 20 centimeters above the ground.

Second, the whole planting and sowing nursery to choose flat terrain, drainage and irrigation conditions are good sandy loam. The first winter plowing, winter plowing applies 3,000 kilograms of perishable farmyard fertilizer every 667 square meters, before spring nursery, apply 20 kilograms of urea, and then shallow tillage. For smashing and smashing, smashing things in and out, squatting 20 cm wide, smashing 15 cm high and smashing 80 cm wide. At the end of February and early March, the earthworms were irrigated with water. After the water seepage, the soil was sprayed with 200 times 50% carbendazim and sowed at a spacing of 20 cm. After sowing, the wet fine sand of 0.2 cm to 0.4 cm was evenly covered. Cockles and poison baits, control of underground pests.

3. The management of buckle sheds and buckle sheds shall promptly detain small arch sheds after sowing and pay attention to keep the soil moist and remove weeds. When the seedlings have 2 to 3 true leaves, they can grow seedlings and grow to 4 to 6 leaves. Pay attention to ventilation during high temperatures during the day. Ten days to 15 days before uncovering, the seedlings are to be planted. In late April, the uncovered land will be uncovered on cloudy days.

4. Grafting In late May to mid-June, grafting was performed using a single bud grafting method. The scion shall be taken from the mature tree of the required variety, and it is required to grow well, fully mature, and full of buds. One-year-old shoots or current year-old branches can be used for scioning. After harvesting, the leaves are immediately cut off, leaving a petiole 1 cm long and kept moist. It is best to use grafting.

When scioning, select a plump bud. Cut the scion 45 cm below the bud at a depth of 3 cm. Then cut it 1 cm below the shoot and cut it straight down. Slightly take the xylem until it cuts at the first knife. Finally, Cut a single bud scion about 1.5 cm above the shoot. Cut the rootstock from 5 cm to 8 cm above the ground and cut it to be smooth and smooth. On the side of the angiosperm cross-section, a small knife with a xylem was cut longitudinally and it was about 2 cm deep, which was basically consistent with the length of the scion noodles. The scion long noodles are aligned with the rootstock cut forming layer, and the film band is tightly packed from the bottom up to expose the buds so that the shoots can be drawn.

V. Post-grafting Management and Precautions After grafting and survival, remove germs in time to reduce nutrient losses. 1 to 2 times of underground dressing, 15 kg of diammonium phosphate per 667m^2 ditch, and 3 to 5 foliar sprays, 0.3% urea in the early stage and 0.3% to 0.5% potassium dihydrogen phosphate in the later stage. Mainly to promote the maturity of dendrite. At the same time, pay attention to loose soil weeding, timely watering in case of drought, pest control. Due to dioecious plants of kiwifruit, it is necessary to mark after grafting or grafting to prevent confusion.

Generally from November to December of the year, nursery stocks can reach heights of 60 cm to 80 cm.
