At present, the pears of many farmers have been harvested and the pear orchards are being cleared. In order to high-quality and high-yield pear trees in the coming year, the pear farmers in various places should immediately apply for the harvesting of fruit fertilizer after the clearing of the pear garden. The fruit fertilizer is the base fertilizer (also called reducing fertilizer).
The time and quantity of base fertilizer application is related to the yield and quality of pears in the coming year. This is because, first, the base fertilizer is the main fertilizer of pear trees. In the pear production cycle, the base fertilizer accounts for the largest proportion of total fertilizer demand; From September to November, the roots of pear trees enter the second growth peak. At this time, fertilization is beneficial to the rapid decomposition of fertilizers, and it is beneficial to the new roots to absorb and store nutrients. Third, the long time of fertilizer absorption can increase the cell fluid. Concentration, improve the ability to resist wintering; Fourth, the fertilizer effect of the base fertilizer is good, can be effectively played in the nutrient critical period of pear trees (April to May), the utilization rate is high; fifth, the nutrient absorption is early, can increase the fullness of flower buds To improve the flower bud quality and fruit setting rate, and to increase the sugar content; sixthly, it can avoid the spring shoots caused by the spring base fertilizer, causing freezing damage. In order to apply the basic fertilizer of the pear tree, we should do the following:
Choose the best fertilization time: before the germination of the pears from the post-harvest to the spring, the base fertilizer can be applied, but the fertilization is the best period in autumn, and the fertilization is recommended when the oysters are good in September and November.
Use high-quality organic fertilizer: the application of organic fertilizer, one can improve the soil, the second can improve the soil fertility, and the third can reduce the inorganic fertilizer to be fixed by the soil and improve the fertilizer supply capacity. Generally, each pear tree is fertilized with soil fertilization or poultry and livestock manure about 100 kg, with phosphate fertilizer 2 kg, nitrogen fertilizer 1 kg, or different types of bio-organic compound fertilizer and high-energy compound fertilizer 10~30 kg. The base fertilizer should account for 60%~70% of the annual fertilizer consumption of pear trees.
Flexible application of fertilization method: The application method of base fertilizer is applied flexibly due to tree age and local habits. First, the pear tree with new fruit can be fertilized by ring; the second is fertilization according to the direction of root system; the third is between rows of pear trees. Ditching; the fourth is to dig deep. These methods are applied alternately between years. In order to reduce the waste of fertilizer, one must apply deep, combined with autumn and winter to deepen the application of 30-50 cm; Second, in the case of drought, timely irrigation, to achieve water and fertilizer.
