[0003] Yam is becoming more and more popular in domestic and foreign markets, and the market capacity is increasing year by year. However, the current problem in yam production is that the proportion of organic fertilizers used in various yam production areas in the country is getting smaller and smaller, and the application of chemical fertilizers is relatively blind. The amount of chemical fertilizers, The types are relatively random

This kind of blind fertilization regardless of the characteristics and laws of yam growth and the characteristics of the cultivation soil has caused serious instability in the yield and quality of yam, and has also caused adverse eff...

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.

Example Embodiment

[0009] Hereinafter, the present invention will be described in detail through specific embodiments.

[0010] For each yam, the composition and ratio of the special compound fertilizer are the same, but the application amount of different yam is different in the specific application process.

[0011] Examples of applying the present invention to fertilizing yam

[0012] The formula is (the following parts are parts by weight):

[0013] 45 parts urea, 30 parts diammonium phosphate, 20 parts potassium sulfate, 0.6 parts zinc sulfate, 0.8 parts manganese sulfate, 5 parts heavy superphosphate, 100 parts river sand.

[0014] The preparation method of the yam special fertilizer is:

[0015] Purchase chemical fertilizers such as urea, diammonium phosphate, potassium sulfate, zinc sulfate, manganese sulfate, and heavy superphosphate from the market. The quality is required to meet the national fertilizer production standards. River sand is purchased from the market. The river sand production area mentioned here is The Chaobai River in Shunyi District, Beijing, is mainly composed of minerals such as quartz, feldspar, mica, etc. The main chemical composition is silica. The content of silica in the river sand is required to be above 50%, and there is no pollution. screen. Mix the above-mentioned chemical fertilizer and Heshayi formula evenly, pass through a 5 mm sieve, dry, and bag the finished product.

[0016] This product can be used as base fertilizer and top dressing for yam. When making base fertilizer, the fertilizer should be applied to the soil layer within 50 cm from the soil surface, and the mixture should be evenly mixed, generally every 667 meters. 2 Apply 40 kilograms of special compound fertilizer; as top dressing, the fertilizer should be applied in the range of 10-30 cm on both sides of the plant, and should be shallowly buried with soil to prevent root burning. Generally, top dressing twice, every 667 meters 2 Apply 10 kg of special compound fertilizer. Applying this fertilizer according to this method can make the yield per mu of yam not less than 2500 kg.

[0017] Examples of applying the present invention to yam yam fertilization

[0018] The formula and preparation process are the same as those in the previous embodiment, and will not be repeated here.

[0019] When this product is used as a base fertilizer for yam medicine, the fertilizer should be applied to the soil layer within 50 cm from the soil surface and mixed evenly, generally every 667 meters 2 Apply 50 kilograms of special compound fertilizer; for top dressing, the fertilizer should be applied within 10-30 cm on both sides of the plant, and should be shallowly buried with soil to prevent root burning. Generally, topdressing is twice, every 667 meters 2 Apply 12 kg of special compound fertilizer. Applying this fertilizer according to this method can make the yield of yam medicine per mu not less than 2800 kg.

[0020] Ordinary fertilizer can only use about 60% when applied to the soil that year, but the river sand in the fertilizer of the present invention has the effect of improving soil quality, so that the utilization rate of the fertilizer in the present invention reaches about 80% in the current season, and the utilization rate in the current season is high.

[0021] It can be seen from the above-mentioned examples that the present invention has a wide range of application, strong and long-lasting fertilizer efficiency, high seasonal utilization, and the river sand in the formula has a significant improvement effect on the soil texture, enabling various yams to achieve high-quality and stable production, overcoming the past The special fertilizer for yam has poor formula adaptability, low nutrient content, low utilization rate in the season, destroys soil texture, and cannot adapt to the shortcomings of normal growth and development of different types of yam in different cultivation environments.
