How to prevent fruit cracking in Shatang mandarin? What good methods are there to prevent Shatang mandarin fruit cracking? Please give an introduction.The methods for preventing and controlling Shatang mandarin fruit cracking can refer to the following list:
1. Apply less phosphate fertilizer, increase the application of potassium, fertilizer, and farmyard manure. From late July to early August, dig 30-40 cm deep holes on both sides of the canopy of bearing trees, and apply 30 kg of human and livestock manure. 0.2 kg of urea, 0.2 kg of potassium chloride, or 3-5 kg of plant ash can also be used to replace other potassium fertilizers.
2. From July to August, irrigation should be carried out for drought resistance. First use a sprayer to wet the canopy, then irrigate. Crop straw and weeds can be used to cover the ground. In winter, the mulch should be turned and buried into the soil along with orchard clearing as fertilizer.
3. In the early stage of drought, shallow plow 8-12 cm within the tree disk, and deep plow 15-25 cm between rows. Drain accumulated water promptly after rainfall.
4. Properly shorten and pinch off overly long branches and shoots. Excess summer and autumn shoots should be removed promptly when they sprout to about 2 cm.
