It is the right time for big cherry to apply base fertilizer in autumn.
When it comes to the essentials of applying base fertilizer in autumn, we should first highlight the word "early". It is generally carried out from September to October, but the effect of early application in September is the best. Because, during this period, the soil temperature is relatively high, the root system absorbs fertilizer for a long time, and the absorption rate is also fast. To grasp the time of fertilization, it is necessary to increase the amount of fertilizer. Agricultural technicians pointed out that 70% of the amount of fertilizer applied in the whole year came from the application of base fertilizer in autumn during this period. Might as well apply more high-quality organic fertilizers, such as rotten soybeans, bean cakes, chicken manure, pig manure, etc., the amount of organic fertilizer per mu should reach more than 3000 kilograms. If the source of organic fertilizer is insufficient, you can buy finished organic fertilizer instead. Moreover, the nutritional supplements in the growth process of big cherries should be more balanced. If we have mastered the time, type and amount of base fertilizer applied in autumn, it is not a great success. Only when combined with scientific fertilization methods can we get twice the result with half the effort. Han Mingjian, director of the fruit tree station of the Fushan District Agricultural Bureau in Yantai City, Shandong Province, said: "the application of basic fertilizer in autumn should be based on radial ditches. 6-8 radial ditches can be dug around the crown, with a depth of 20-30 cm, and as many and deeper as possible when digging ditches. This will help the roots to absorb more nutrients. At the same time, the organic fertilizer should be evenly mixed with the soil as far as possible, and keep the soil in close contact with the fertilizer, so that the fertilizer effect can be better developed. " In addition, agricultural technicians also suggest that fruit farmers should bury the soil and water in time after fertilization, which is conducive to the combination of fertilizer and water and improve the utilization rate of fertilizer.
