Abstract
The invention discloses compound fertilizer special for Chinese yam. The fertilizer is prepared from, by weight, 45 parts of urea, 30 parts of diammonium phosphate, 20 parts of potassium sulphate, 0.6 part of zinc sulfate, 0.8 part of manganese sulfate, 5 parts of triple superphosphate and 100 parts of river sand, wherein urea, diammonium phosphate, potassium sulphate, zinc sulfate, manganese sulfate and triple superphosphate are used for providing mineral nutritional components for the growth of Chinese yam, and river sand is used for improving cultivation soil texture, at least comprises silicon dioxide with content of 50% or above, and is screened by a 5-mm screen. The compound fertilizer is wide in application range, strong and lasting in fertilizer efficiency and high in in-season utilization rate; river sand in the formula has a remarkable effect on improving soil texture, various types of Chinese yam reach high quality and stable yield, and the defects that an existing fertilizer formula special for Chinese yam is poor in adaptability, low in nutrient content and low in in-season utilization rate, damages soil texture, can not adapt to the normal growth and development of different types of Chinese yam in different cultivation environments and the like are overcome.
