Embodiment 1

[0057] Special fertilizer contains N, P 2 o 5 、K 2 The ratio of O is 2:1:1. Every 100g of fertilizer contains 23g of urea, 14g of diammonium phosphate, and 63g of power plant ash. After the required raw materials are mixed evenly according to the above ratio, they are immediately applied to the soil, watered after covering the soil, the same below.

Embodiment 2

[0059] Special fertilizer contains N, P 2 o 5 、K 2 The ratio of O is 4:3:0.5. Every 100g of fertilizer contains 35g of urea, 38g of diammonium phosphate, and 27g of power plant ash.

Embodiment 3

[0061] Special fertilizer contains N, P 2 o 5 、K 2 The ratio of O is 10:3:3. Every 100g of fertilizer contains 35g of urea, 12g of diammonium phosphate, and 53g of power plant ash.

Abstract

The invention discloses a special fertilizer for populus tomentosa seedlings and a preparation method thereof. The fertilizer takes power plant ash as a potassium source, has the advantages of balanced N, P and K proportion, comprehensive and balanced fertility and obvious effect on promoting the growth of populus tomentosa, and can be used for improving the yield and quality of populus tomentosa and ensuring the high seedling quality index. As the fertilizer takes the power plant ash obtained after utilizing the cotton stalk resource for power generation as the source of potassium fertilizers, not only can the power plant waste be turned into wealth, so that the whole cotton stalk resource is effectively recycled, but also the bulk blending fertilizer prepared with the waste power plant ash as the source can be used for reducing the environmental pollution and lowering the fertilizer production cost.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a special fertilizer for poplar tomentosa seedlings and a preparation method thereof. Background technique [0002] Fertilizers include basic fertilizers and chemical fertilizers. Basic fertilizers mainly include nitrogen fertilizers, phosphorus fertilizers, and potassium fertilizers; chemical fertilizers mainly include compound fertilizers and mixed fertilizers (fertilizers containing trace elements and organic and inorganic compound fertilizers), etc. Compound fertilizers are processed by chemical methods, such as ammonium phosphate, nitrophosphate fertilizer, potassium nitrate, potassium dihydrogen phosphate, etc.; mixed fertilizers are several simple chemical fertilizers and or binary compound fertilizers, which are mainly processed by physical methods. Compound fertilizer is the general term for compound fertilizer and mixed (mixed) fertilizer. The compound f...
