How Pear Tree Formula Fertilizes

Fertility requirements for pear trees The growth of young branches and leaves of pear trees is large and requires more nitrogen. As a result, the fruits of large trees need more phosphorus and potassium. In addition, pears require large amounts of potassium, calcium, and magnesium. The demand for potassium is equal to that of nitrogen. The requirement for calcium is close to nitrogen, and the requirement for magnesium is smaller than that of phosphorus and larger than other elements. Therefore, pay attention to increase potassium fertilizer and calcium fertilizer. There are two peak periods for nitrogen requirement for pear trees in the year. The first peak is in May and the second peak is in July. Phosphorus only has a small peak in May throughout the year. There are also two potassium requirements. The peak period is the same as nitrogen.

Pear Tree Formula Fertilization Technology Medium Fertility Level Pear Tree Annual Fertility Cycle Mu Fertilizer Application Organic Fertilizer 3000～3500kg (or Commodity Organic Fertilizer 400～450kg), Nitrogen Fertilizer 16～17kg, Phosphor Fertilizer 6～8kg, Potash 8～ 10 kg. Organic fertilizer is used as a base fertilizer, nitrogen and potassium fertilizers are used as base fertilizers and secondary topdressing, all base fertilizers for phosphate fertilizers are used, and chemical fertilizers and manure (or commercial organic fertilizers) are mixed and applied. Basal fertilizer: Basal fertilizer is dominated by organic fertilizer, with suitable quantified fertilizer. General Mushi farmyard fertilizer 3000 ~ 3500 kg or commodity organic fertilizer 400-450 kg, urea 5 kg, 13 ~ 17 kg of ammonium phosphate, potassium sulfate 5 ~ 6 kg. Top dressing: Fertilizer top dressing, Mushi urea 13 ~ 14 kg, potassium sulfate 7 ~ 8 kg. During fruit enlargement, topdressing: Mushi urea 10 ~ 11 kg, potassium sulfate 4 ~ 6 kg. Fertilizers outside the roots: Boron deficiency can be sprayed once at a flowering stage with a concentration of 0.3% to 0.4% borax aqueous solution. The application of zinc fertilizer has a significant effect on the treatment of lobular diseases in fruit trees. It can be used with a 3% to 5% aqueous zinc sulfate solution before and after germination in the spring. Spraying iron can be sprayed with a mixture of 0.3% ferrous sulfate and 0.5% urea and sprayed once a week in the high season.
