Problems solved by technology

Due to long-term excessive fertilization, soil compaction and acidification are caused, and pests and diseases increase, which directly affect the growth of plant roots and the absorption of fertilizer nutrients, resulting in a vicious cycle of fertilizer waste. A polyuronic acid ecological fertilizer additive and its application are proposed.

Embodiment 1

[0038] An application of a polyuronic acid ecological fertilizer additive, comprising 99.4-99.9% of urea and 0.1%-0.6% of an additive, the additive comprising 60% of polyuronic acid and 40% of modified lignosulfur Sodium acid, compounded sulfonate compound, humic acid and borate mixture, additives are prepared into a 30-50% solution, added to the bottom of the U-shaped tube of the urea evaporator with a metering pump, and made by two steaming and urea towers The finished product polyuronic acid urea is obtained.

Embodiment 2

[0040] An application of a polyuronic acid ecological fertilizer additive, comprising 99.1-99.7% of compound fertilizers and 0.3%-0.9% of additives, said additives comprising 70% of polyuronic acid and 30% of modified lignin Sodium sulfonate, compounded sulfonate compound, humic acid and borate mixture are added to the granulator after being measured by a weighing scale, and then granulated, dried, sieved and wrapped with an anti-caking agent. The finished polyuronic acid compound fertilizer has a N-P2O5-K2O nutrient distribution ratio of 29-6-7.

Embodiment 3

[0042] The polyuronic acid urea prepared by example 1 is mixed with 0.5% solution, selects two adjacent plots 10m in the same bean planting field, sprays with 5kg common urea solution and polyuronic acid urea solution blade respectively at the seedling stage Once, the leaves are sprayed once every 15 days during the flowering and fruiting period, each time with 15kg, and other field management, fertilization and pest control are the same. The test results are:

Abstract

The invention discloses a glyuronic acid ecological fertilizer aid and application, and belongs to the technical field of fertilizer aids, and the glyuronic acid ecological fertilizer aid is prepared by proportionally preparing and processing glyuronic acid, modified sodium lignin sulfonate, a compounded sulfonate composite material, humic acid and boric acid. According to the invention, glyuronic acid and modified sodium lignin sulfonate can be adsorbed on the surface of a common fertilizer after being mixed with the common fertilizer, so that fertilizer particles form a good dispersion system under the action of electrostatic mutual exclusion, and trace metal ions can be chelated; furthermore, particles in a common fertilizer can form a stable solution body fluid after being dissolved in water, phosphorus fixation is reduced, precipitation is avoided, and the utilization rate of fertilizer nutrients is increased; the fertilizer added with the glyuronic acid ecological fertilizer aid has the effects of stress resistance, disease resistance, root promotion and growth promotion.

Description

technical field [0001] The invention belongs to the technical field of fertilizer additives, in particular to a polyuronic acid ecological fertilizer additive and its application. Background technique [0002] Some invention patents in the technical field of fertilizer additives are disclosed in the prior art, among which the invention patent with application number CN105198560B discloses fertilizer additives and their applications. The fertilizer additives designed by this patent are one of the very important raw materials for new fertilizers , can reduce the frequency of fertilization and improve efficiency. It plays an indispensable role in improving the quality of fertilizer products, increasing the functions of fertilizer products, improving the effect of fertilizer application and increasing the utilization rate of fertilizers. It is very important to promote the development of modern agriculture, improve resource utilization and improve the impact of fertilizer applic...
