1, strengthen fertilizer and water: in dry weather, plants with small fruits should be watered in time to keep the soil moist, which is beneficial to nutrient absorption and fruit expansion.
While keeping the soil moist, 65,438+000 kg of plants can be drenched with 65,438+0-65,438+0.5 kg of 28 or Jinguoshuobaoge 865,438+08+high-potassium water-soluble fertilizer, which can be applied in 2-3 times.
2. Foliage fertilizer promotes greatly: Spraying quick-acting fertilizer on leaves is the most suitable way to supplement nutrition. On the one hand, it can supplement nutrition to promote the maturity of new shoots and fruit expansion, and on the other hand, it can promote coloring and sweetening.
Recommended scheme: Li Shuang or Cape+Baotianfu, the fruit with high potassium content or harvested first, increase the concentration and spray it every 7- 10 days for 2-3 times in total. Spraying the fruit can improve the phenomenon of small fruit to some extent.
Management technology of fruit-bearing period of sugar orange
1, according to the tree potential to decide whether to apply spring bud fertilizer and the amount of fertilizer; Spraying boron fertilizer and zinc fertilizer on leaves at flowering stage can improve flower quality and pollination rate and reduce the difficulty of fruit preservation.
2. Determine the application amount of fruit-stabilizing fertilizer according to the fruit hanging amount and tree potential;
3. Grasp the girdling time and control the number of summer shoots;
During the critical period of fruit expansion in April, June, July and August, pay special attention to the supply of fertilizer and water;
5. According to the tree potential and the number of fruits, reasonably comb the fruits, reasonably arrange the release time of autumn shoots in combination with the supply of fertilizer and water, fertilize autumn shoots in advance, and cultivate strong autumn shoots to prepare for next year's results;
6. Control the late autumn shoots and winter shoots in time to avoid affecting the quality of flower buds in the coming year;
7. Supplementing medium and trace element fertilizers in the young fruit stage and color-changing stage to promote the early saccharification and color-changing of fruits and early listing.
