First, the choice of species: should choose the breeding period of 220 days or more varieties. If you choose 160 to 180 days of the variety, after the planting, in January of the following year can be the ball, when the weather is cold, the flower ball is vulnerable to frost damage.
Second, sowing nursery: When nursery seedlings must be shade moisturizing, every 7 days during the treatment of a worm. In order to avoid pest damage, it is best to use insect nets to cover the seedbed. The seedlings in the seedbed should not be too crowded, and the distance between the seedlings should be 10 cm, so as to cultivate strong seedlings and avoid the formation of tall seedlings, so as to prevent the plants from freezing injury in the winter. When the seedling age reaches 30 days, 5 to 6 leaves of the seedlings must be planted in time.
Third, pre-winter management: After planting to mid-October, pay attention to pest control. The control of wheat moth can be sprayed with 5% Frigid 1000 times solution, preventing Brassica juncea 20% cypermethrin 1000 times and diluting 2000 times. Before winter, in the management of water and fertilizer, it is necessary to promote the combination of control and ensure that the plants grow 18 leaves before the next frost. Pour frozen water before freezing.
Fourth, the spring management: early spring air warming after early watering, early dressing, after the ball water and fertilizer supply should be sufficient, pouring water once every 7 days, every 2 times the water should be topdressing 1 times. In addition, it is also necessary to cover the ball with folding leaves to prevent the flower bulbs from being dried. When the flower bulbs are sufficiently large, they must be harvested in time to prevent scattered flowers and affect their merchandise.
