Sakya fruit with live seedlings directly planted, the source of seed is very important, the seed should come from good varieties (common Sakya fruit) productive, high-quality mother plant on the large and fruit-shaped fruit, preferably with the same varieties of artificial pollination of the fruit. When the fruit is fully ripe, the fruit becomes light greenish-yellow, and the suture between the small fruits is obvious, the seed is harvested and collected. Cultivated as a grafting rootstock, seed collection can be less demanding. Seeds taken out and washed, remove unsubstantial and small seeds, drying that is sown, the following spring sowing of seeds to be fully sun-dried, and then placed in a polyethylene plastic bag, sealed and preserved.
Two, Sakya fruit sowing time
In the winter temperature higher areas Sakya fruit is best 8 ~ September seed harvesting and drying that is sown, fresh seed germination rate is higher, the seedling growth period is long, and is conducive to cultivate strong seedlings. In order to cultivate strong seedling before sowing can be used 200mg Chanku gibberellin soak seed 24~36 hours, can advance seedling 3~5 days, seedlings 6 leaves and then to love more collection 5000~6000 times foliar spraying 2 times can effectively improve the rate of strong seedlings. Due to the release of fruit seedlings more sensitive to frost, so the fall sowing seedlings should pay special attention to the cold insulation work. Other southern subtropical areas are best for spring sowing, generally to the local low-temperature rainy weather has passed, sunny and warmer more stable after sowing is good.
Three, saga fruit sowing method
The stored saga fruit seeds before sowing to sun, in order to promote germination, the nursery should be selected to sunny, well-drained, fertile sandy loam, with gentle slopes on the ground for the best. Nursery land before sowing should be deep tilled and sunned for 1~2 months, and then a small amount of rotted organic fertilizer and lime as a base fertilizer, broken up and mixed, and then repair furrows and beds. Strip sowing, sowing can be, with 7-8 kg of seed per acre. Covered with river sand or fine soil, slightly compacted and drenched with water to cover grass or plastic film, the seedbed attention to moisture, but also afraid of stagnant water, so we should also pay attention to prevent excessive moisture, so as not to cause root rot. After germination, uncover the cover grass or plastic film, so as not to bend the seedlings.
Four, the release of fruit seedling management
1. drenching fertilizer: seedling period of 3 days or so need to drench 1 time, such as drought needs to be 1 time a day, to 6 ~ 8 leaves can be applied to dilute fecal water or 0.5% urea soluble in water, and then gradually increase the concentration of the nursery later, but also need to drench potash or compound fertilizer, in order to facilitate the cultivation of strong seedling. Fertilizer should be weeded and loosened before application.
2. Pest control:Sakka fruit seedling pests occur less, but diseases often occur, especially root rot. Therefore, the seedling period should pay attention to the prevention and control, to prevent excessive shade and water immersion, and pay attention to the prevention of drenching with metribuzin.
