Autumn is the time to cultivate winter jujube seedlings. The survival rate of cultivated winter jujube seedlings during this period is very high. However, it will also show the state of death. In order to enable us to improve the survival rate. First, we should fertilize the land before farming to ensure that the soil is fertile. After the fertilizer is completed, it needs to be planted and can be planted after completion. When planting winter jujube seedlings, we should immediately sprinkle water so that the roots of winter jujube seedlings can better absorb nutrients. But don't apply fertilizer right away, you must know that winter jujube seedlings have just come into contact with new land. The land contains a lot of fertilizer. It has been absorbed by the small winter jujube seedlings. If it is on the fertilizer, it is very simple and will lead to the danger of overnutrition. Spray protection: starting from mid-July, combined with the prevention and treatment of winter jujube seedlings, using mancozeb (Small Killing, Dasheng M-45), 0.15% 梧Numycin, Antaisheng, Kairun, Peracetic Acid Bactericides (effective in 3 days after rain; can also be sprayed once in mid-July with 200 times the same amount of Bordeaux mixture.
