The effect of autumn basal fertilizer in winter jujube garden is good
In actual production, some jujube farmers do not apply basal fertilizer for autumn due to objective reasons or fertilization habits. The application time of basal fertilizer was extended from autumn to the following spring. Years of practice have shown that this habit is not good, and winter jujube or basal fertilization in autumn is effective. 1. The autumn base fertilizer is beneficial to the decomposition of organic fertilizers. Before and after the autumn fruit harvest, the temperature and the ground temperature are still relatively high. It is suitable for the propagation of microorganisms, which can accelerate the decomposition of organic matter in the soil and release various nutrients required by winter jujube trees. 2. Base fertilizer in autumn is beneficial to wound healing. After picking the winter jujube trees, there is still a period of time before the soil is frozen. The application of basal fertilizer at this time is conducive to the growth of the root system, and the root and root-cut wounds are easily healed due to fertilization, which can reduce the invasion of the plants by the bacteria. Improve disease resistance. 3, autumn Shiji fertilizer is conducive to the absorption and accumulation of nutrients. After autumn basal fertilization, due to the decomposition of organic fertilizer and appropriate amount of chemical fertilizer input, it can meet the demand of winter jujube tree for nutrition, supplement the nutrient that the tree body consumes after a large number of results, promote the restoration of tree vigor and nutrient accumulation of tree body, and improve winter jujube The tree's ability to resist cold and freeze.
