Seed collection
Will be fully matureWild kiwifruitAfter the fruit is picked up, it is put in a cool place to be soft and ripe, and then peeled off. It is put in a clean gauze bag to scrub, and the pulp is washed away, leaving only seeds.Spread the seeds to dry, pack them with plastic bags, and store them at a low temperature of 4-5 ℃ for standby.
Sand reservoir
About a month and a half before sowing (usually in late December in Meixian County), take out the dried and stored seeds and soak them in hot water at 50~70 ℃ for 1~2 hours, then soak them in cold water for 1~3 days. Take out the seeds and mix them with 5~10 times of wet river sand and put them into a basin or bucket. Turn them every other week and maintain proper humidity. Hold them in a ball and let them loose.
sow
FebruaryEarly ten daysSow at the beginning of spring.The sandy loam soil with sufficient light, fertile and loose soil, convenient drainage and irrigation, slightly acidic or neutral is selected as the seedbed, and basic fertilizer and pesticide are applied before the whole border.The car shall be made by deep raking and fine leveling, and the high car shall be made to prevent water stains.Spread the seeds with sand evenly on the nursery, cover a layer of 2-3 mm thick fine soil, and finally cover with plastic film.
watering
The seedbed shall be kept moist for a long time. Water shall be sprayed once in the morning and evening on sunny days. In order to prevent the soil from hardening and washing out seeds, water shall be sprayed frequently, carefully and evenly.About 20 days after sowing, some arched soil will emerge. At this time, the plastic film needs to be arched into a small arched shed. In sunny days, the two ends will be opened at noon for ventilation.When 80% of the seedlings emerge, remove the plastic film.
Transplantation preparation
The requirements for transplanting nursery land shall be consistent with that for seeding bedCompartmentThe car surface is 50cm higher than the ditch, and the width is 60-80cm.The seedbed shall be provided with a trench of more than 50cm to prevent waterlogging in summer and root damage.
Thinning seedlings
After the seedlings are unearthed, they are generally too dense. In order to ensure that the seedlings are neat and strong, the seedlings should be properly thinned when there are 2~3 true leaves, and the weak ones should be removed, the strong ones should be retained, the disease should be removed, and the crooked ones should be retained.
Post planting management
When the seedlings grow to 4-5 true leaves, they can be transplanted with soil in cloudy or light rainy days, and the row spacing is 10cm × 20cm.Kiwifruit seedlings are delicate and need to be prevented from drying, drought and rain. After transplanting, they should be covered in sunny days, daytime and rainy days, and the shade net should be uncovered at night, cloudy days and light rainy days.When seedlings grow 5~6 true leaves, the shading net can be gradually removed.One month after transplanting, spray 0.1%~0.3% urea plus 0.1%~0.3% urea every 15 days or soPotassium dihydrogen phosphateWater can promote the growth of seedlings.When the seedling height is 15~25cm and 10~15 leaves are taken off, remove them in timeAxillary budAnd promote the seedlings to thicken for grafting.
Disease and insect control
Kiwifruit is vulnerable toDamping off disease、Mole cricketandGeotigerInfringement of.Rhizoctonia solani: the base of the affected seedlings was initially waterlogged, then gradually deepened, then became black, constricted and decayed, and the upper leaves withered and gradually the whole plant died.Spray 50% carbendazim 1000 times or 50% for 2~3 times in combination with water sprayThiophanate methyl1000 times liquid control.
Mole cricket:Larvae lie in the daytime and rise at night, gnawing the young leaves and biting off the stem, causing the seedlings to die.It can be cooked at 10:1branMix with trichlorfon powder and sprinkle it around the plant or trap with light.
Land tiger:After the 3rd instar, the larvae bite off the stem of the seedlings in the daytime and emerge at night, causing seedling defects.It can be killed manually in the morning, or sprayed with 1% trichlorfon solution by spraying water or sprayed in the nursery with 1% trichlorfon solution mixed with vegetable leaves.
