Recently, in Shipan Village, Foping Town, Dadukou District, Chongqing, the citrus blossoms are rich. Expert Li Shixiang explained the management points of citrus in spring for the villagers. He said that nowadays citrus is in full blossom, and after flowering, it is necessary to give thanks to fertilizer, in order to increase citrus yield and improve citrus quality.
Fertilizer
Citrus is an evergreen tree species. Citrus sprouting, flowering, fruiting and so on all need to consume a large amount of nutrients. Therefore, it is necessary to supplement fruit tree nutrition according to different growth stages. “Last year, our village’s Chunjian had fewer fruits and generally reduced production. The number of citrus blossoms this year has been relatively high. Conversely, last year's citrus trees with more fruit were less in bloom this year.†Li Shixiang said that no matter how many flowers are spent, If the management procedures of Xie Hua Fei are reduced, the yield and quality of citrus will be affected.
Fertilizer to be applied
"So how to use fertilizer should be applied? Generally in the 7 to 10 days after the Xiehua can be fertilized." Li Shixiang said, Xie Hua Fei to apply decomposed organic fertilizer, combined with the application of available nitrogen and potassium.
Li Shixiang also emphasized that when applying fertilizers, it is necessary to pay attention to a "skillful" character, and it is necessary to judge how to apply stable fruit fertilizer according to the growth of citrus trees. If citruses with many fruits and weak vigor are harvested last year, they must fertilize them in time. Each farmer should use farmyard manure, apply high-quality 45% sulfur-containing compound fertilizer 300-800 g, dig a radial groove 20-40 cm deep, and combine leaves. Outside the root top dressing 0.5% urea, plus 0.2% potassium dihydrogen phosphate; If the citrus leaves dark green color, vigorous tree, with less fruit last year, you can apply less or not, but at the same time to properly add trace elements magnesium , zinc, boron and so on.
“After flowering, Xiehua Fei can also apply special formula fertilizer for high-nitrogen citrus to supplement the nutrients consumed during the flowering period.†Li Shixiang said that in addition to the application of Xiehua Fei, the spring citrus should also take care to exclude the water in the low-lying citrus orchards, avoiding The accumulation of water after the rain affected the growth of the roots and caused the fruit to fall.
