Abstract

The invention belongs to the field of fertilizers, and particularly relates to a dedicated formula fertilizer for ratoon rice. The dedicated formula fertilizer is characterized by comprising the following effective elements by weight according to pure nutrient: 26.0-20.0 % of nitrogen, 8.0-5.0 % of phosphorus pentoxide, 20.0-16.0 % of potassium oxide, 8.0-3.0 % of silicon dioxide, 4.0-2.0 % of calcium oxide, 4.0-2.0 % of magnesium oxide and 0.5-0.3 % of zinc, and 0.2-0.1 % of farm-oriented brassinolide as a plant growth regulator. Compared with the prior art, the dedicated formula fertilizer for ratoon rice is high in nutrient content, reasonable in nutrient ratio and appropriate in nutrient form of nitrogen and phosphorus, and can obviously promote ratoon rice axillary bud to bud and increase the fringe cultivating number. Through the application of the dedicated formula fertilizer, the output of ratoon rice per hectare is increased to 259-368 kg, the increased income amount is converted into renminbi 631-725 yuan, and the fertilizer utilization ratio is increased by 14.1 % to 27.3 %.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a special formula fertilizer for ratooning rice. Background technique [0002] my country is a major rice production and consumption country in the world. Rice cultivation area accounts for 1 / 3 of the food crop cultivation area, and its output accounts for nearly 1 / 2 of the total grain output. Ensuring the stability of rice cultivation area and production is related to the overall situation of national food security. However, in recent years, with the adjustment of the planting industry structure and the increase of labor costs, the sown area of ​​rice in my country has changed greatly, especially in some provinces, the sown area of ​​double-cropping rice has decreased significantly, which has caused hidden dangers to national food security. [0003] Using the regenerative characteristics of rice, ratooning rice is harvested after the first season of ...
