Fertilizer is the basis of peach production. In order to obtain peaches with good fruit and high yield, it is necessary to start from the peach tree growing season. How can peaches fertilize?
1, base fertilizer. Peach tree application time is generally between mid-September and early October. In the fruit-producing period, the farmer’s fertilizer is 2 kg of fertilizer, at least pounds of fruit and fat. It is best to mix some quick-acting fertilizers when applying farmer's fertilizer (the ratio of quick-acting fertilizer is N:P:K=7:5:9. The investment in mu is 200-300 yuan).

Specifically: First, the flower before the fertilizer. Nitrogen-based, 100 kg of high-quality compound fertilizer per acre. The second is the first rapid growth of the fruit. Nitrogen is mainly combined with a small amount of phosphorus and potassium fertilizer, and 100 kg of high-quality compound fertilizer is applied per mu. (Thanks to the fertilization within a week). The third is the second rapid growth period of the fruit, mainly based on nitrogen and potassium, and 100 kg of high-quality compound fertilizer. The fourth is post-harvest fertilizer, 100 kg of high-quality compound fertilizer, and phosphorus and potassium as the appropriate amount of nitrogen fertilizer. The depth of fertilization is 10cm.

After flowering, combined with control of pests and diseases, spray 2-3 times of 0.3% urea, spray 2-3 times of 0.3% potassium dihydrogen phosphate from the middle to late stage, and spray 1-2 times of amino acid calcium fertilizer during fruit expansion period. 1-2 times of urea, then spray potassium dihydrogen phosphate, swelling period spray amino acid calcium fertilizer).
