Chestnut application reduces the empty rate
Chestnut "empty" problem has a great impact on the output of chestnut. At present, in addition to artificially assisted pollination during the flowering period of chestnuts, there is a truly effective method of applying boron fertilizer. I. Types of Boron Fertilizer and Boron Application Methods Boron fertilizer is commonly used in borax, containing 10.8% boron, soluble in warm water, boric acid, 16.8% boron, white crystals, soluble in water. Boron applied in the soil is fertilized by annular grooves or radiation grooves, and the depth of the groove should be 20 to 80 cm. In the event of rain or the combination of irrigation and boron application, it is not necessary to dig fertilization ditch. Since the effective period of boron application in soil is as long as 2 to 3 years, the effect of that year is not very significant. Therefore, it is necessary to combine it with foliar spraying. Foliar spray borax concentration of 0.1% to 0.3%, boric acid 0.1% to 0.5%. Second, the period of application of boron, climate and application rate in mid-April each planting age of about 0.1 kilograms of trees, pay attention to the amount of application per acre should not exceed 12 kilograms, otherwise it will cause chestnut poisoning. It is deep in the sunny days and shallow in the rain. The foliar spray is applied once at the beginning of June and at the flowering stage. It is better to spray on cloudy days in high temperature weather. Sunny days should be sprayed on the back of leaves before 10 o'clock in the morning or after 4 o'clock in the afternoon. Do not spray on rainy days. If combined with 0.3% urea, 0.3% -0.5% superphosphate, the effect will be better.
