Seed seedling method and management methods for kiwi seedlings
1. Kiwi seed collection method:Select fully mature fruit from robust mother trees, wait until it softens, then separate the seeds from the flesh, wash them clean and dry them in the shade for later use.
2. Kiwi seed treatment method:40 days before sowing, soak the shade-dried seeds in 45°C warm water for one day and night. Place wet sand at the bottom of a flower pot (it is best if the sand just releases water when held in the hand), then spread the seeds evenly on top, alternate in layers for sand storage, and cover with asphalt felt.
3. Sowing and management methods for kiwi seeds:Sow in early spring of the following year. Before sowing, apply sufficient base fertilizer at 4000 kg to 5000 kg per mu, irrigate thoroughly, and sow after the water has seeped down. Because kiwi seeds are small, it is best to mix them with sieved fine nutrient soil for drilling. The row spacing is 15 cm, the sowing width is 20 cm, and the sowing rate is 1 gram per square meter. After sowing, cover with sieved fine soil 2 mm to 3 mm deep, and cover with straw so as to keep the soil moist at all times.
4. Management methods after kiwi seedlings emerge:After the seedlings emerge, the mulch should be removed promptly. When the young seedlings grow 3 true leaves, thin and transplant them, with a seedling spacing of 10 cm to 15 cm. The remaining seedlings can be transplanted with soil for separate planting. During the seedling stage, apply thin fertilizer frequently. When the diameter of the seedling reaches 0.5 cm, grafting can be carried out. Softwood cutting seedling cultivation. Cutting time. The best time for softwood cutting is mid-June and mid-September. In addition, the peak growth period of kiwi has passed, and the high-temperature weather of summer is also avoided.
II. Kiwi cutting seedling method:
1. Selection and treatment of kiwi cuttings:Select current-year semi-lignified branches free of pests and diseases as cuttings. Keep 2 to 3 buds per branch, keep 1 to 2 leaves at the upper part, and cut the retained leaves in half. The lower cut of the cutting should be made flat or obliquely close to below the node, and the cut must be smooth, then dip the cut in 2×10-4 ABT rooting powder No. 1 solution.
2. Preparation and management of the seedbed:The cuttings should be placed in a location with a good water source, using sieved sandy soil as the bed soil, and disinfect the soil with zineb or potassium permanganate. After leveling the land, build a 2 m high shade shed for shading. After insertion, check at any time to keep the humidity in the shed at 90%. Generally, spray water once in the morning and once in the afternoon on sunny days. Roots form about 20 days after insertion, and after 25 days, 0.2% urea or potassium dihydrogen phosphate can be sprayed for foliar fertilization. After 60 days of cutting, they can be transplanted.
III. Kiwi root cutting seedling method:
Kiwi roots have strong tillering ability. Use root segments dug out during land preparation or seedling lifting to promote the sprouting of rootstock seedlings, thereby saving a large amount of seeds and branches. The method is to cut pencil-thick roots into root segments 10 cm to 15 cm long, with the thick end facing up and the thin end facing down for cutting. The thin end should be trimmed flat with pruning shears. After insertion, they can sprout and take root to form plants. The survival rate is highest when cuttings are inserted in early to mid-April. The preparation of the cutting bed and post-insertion management are the same as the softwood cutting method.
