What to Do If a Pear Tree Does Not Bear Fruit? A Detailed Guide to Practical Technical Measures
1. Avoid excessive application of nitrogen fertilizer. Some farmers grow sweet potatoes between their pear trees; they grow sweet potatoes to cut the vines to feed pigs, so they frequently pour pig manure, and the pear trees grow tall and large but bloom without bearing fruit. For this type of pear tree, nitrogen fertilizer application should be stopped and phosphorus and potassium fertilizers increased; apply potassium dihydrogen phosphate by trenching at the drip line of the canopy and by spraying the canopy.

Key Technical Points and Application Methods of Long-Shoot Pruning in Peach Trees
Long-shoot pruning is a pruning technique that basically does not use heading cuts, and only employs thinning, renewal cuts and long-shoot training. Because heading cuts are basically not used, the current-year shoots after pruning are relatively long, with fruiting branches averaging generally 50-60 cm in length. Long-shoot pruning has the advantages of being simple to

Detailed Explanation of Key Points for Autumn Management Techniques of Citrus
1. Heavy application of fruit-swelling fertilizer: its fertilizer amount accounts for about 30% of the annual fertilizer amount, mainly decomposed organic fertilizer. Dig an arc-shaped ditch 20-30 cm deep and 20 cm wide between rows at 50-100 cm from the main trunk. For large trees, apply 2.5 kg of cake fertilizer and 50 kg of decomposed pig or cattle pen manure or human excrement and urine per tree; for small

Wheat fertilization has its particularities: pay attention to less phosphorus and more potassium
Applying excessive phosphorus to wheat first of all increases costs. This year diammonium phosphate is quite expensive, with the retail price of 64% exceeding 3900 yuan/ton. Phosphorus is essential, but there is no need for excess. Empirical data shows that using 40-50 kg of a ternary compound fertilizer containing 15%-20% pure phosphorus per mu as a base fertilizer generally prevents phosphorus deficiency.

How to reasonably determine nitrogen fertilizer application rates in precision quantitative rice cultivation
The quantification of nitrogen needs to consider the fertilizer requirements of high-yield rice, the pattern of soil nitrogen supply, fertilizer characteristics and the current-season utilization rate, as well as various changes during the growth period, and includes two parts: total nitrogen quantification and nitrogen fertilizer application methods. Determination of total nitrogen amount: obtained through soil testing and fertilizer recommendation trials
