Kiwifruit with red heart: Generally, it ripens from August to September every year. For example, the red-hearted kiwifruit produced in Pujiang, Sichuan Province began to ripen in early August, while Donghong would not ripen until the end of August or early September, and the best eating time was September.
Cui Xiang Kiwifruit: Generally, the maturity period is between August and 65438+ 10 every year, and sometimes it is extended to 165438+ 10 due to weather factors.
Guichang Kiwifruit: 5438+ 10 ripens in the first half of October. Because Guichang kiwifruit is a late-maturing variety, its maturity time is a little later than other varieties of kiwifruit. But it can be refrigerated for 4-6 months after maturity, and can only be preserved for about 30 days without preservation.
Actinidia arguta: August -65438+ 10. Actinidia arguta generally germinates around Tomb-Sweeping Day and matures in September. The average fruit weight after ripening is 18g, and the maximum fruit weight is 33g.
Kiwifruit: 65438+1ripens in the middle of October. The name "Golden Kiwifruit" comes from the yellow flesh after ripening, and it is widely planted in Meixian County, Shaanxi Province, China.
Breeding method of kiwifruit;
Choose a big ripe fruit, ripen it after six or seven days, take out the seeds, wash them with clear water, dry them, wrap them in gauze, and then bury them in slightly wet sand and store them for 1-2 months to improve their germination potential and germination rate. It is best to choose cool, drained and loose sandy soil for nursery. Sufficient base fertilizer should be applied and water should be poured on the soles of feet. The width of the boundary should be 1- 1.2m, and the soil at the boundary should be fine and smooth.
It is more suitable to sow in late February to early March. Before sowing, mix special seeds with some sand and sow 6-8g seeds per square meter. Covered with a layer of 4-5 mm thick fine sand, slightly pressed. Cover with straw and water to keep the soil moist and promote seed germination.
It is best to support an arched plastic film shed above the seedbed to prevent rain impact, reduce water evaporation, and raise the temperature of the seedbed at the same time, which is beneficial to shading, watering, topdressing, loosening soil, weeding and thinning seedlings in time after seeds germinate and emerge.
