Seedling strengthening nutrient agent special for paddy rice

Abstract

The invention relates to the technical field of formula of fertilizer special for paddy rice and discloses a seedling strengthening nutrient agent special for paddy rice. A ton of nutrient agents contain the following constituents by weight: 50-80kg of zinc sulfate, 3.0-6.5kg of ferrous sulfate, 2.5-7.5kg of root accelerant, 2.5-7.5kg of silicon fertilizer, 0.75-4.0kg of uniconazole, 500-750kg of ammonium chloride, 100-149kg of calcium superphosphate, 95-125kg of potassium chloride, 60-100kg of ammonium phosphate and 10-32kg of attapulgite. The invention can provide necessary elements, such as nitrogen, phosphorus, potassium, silicon, iron, zinc and the like, for growth and development of paddy rice, and active substances for promoting root system growth are added so that growth and development of root system of paddy rice can be promoted; proper amount of plant growth regulator ''uniconazole'' is applied so that the rice seedlings can be promoted to be tillered in advance; vegetative growth can be controlled during the middle and late tillering periods to dwarf plants to improve paddy rice falling resistance, promote rice seedling growth, shorten seedling suppression stage and increase economical benefit; and the seedling strengthening nutrient agent special for paddy rice has the benefit of wide popularization.

Description

technical field [0001] The invention relates to the technical field of rice-specific fertilizer formulations, in particular to a special seedling-strengthening nutrient for rice. Background technique [0002] Fertilizers and fertilization are very important in agricultural production. Chemical fertilizers account for 30%-40% of the increase in crop production. At present, ordinary compound fertilizers are generally used as base fertilizers in the early stage of rice transplanting or direct-seeding rice, but ordinary compound fertilizers cannot It effectively solves the problems that the slow seedling period of rice is longer when transplanting, and the problems of yellow and thin seedlings and multiple stiff seedlings in the early stage of dry direct seeding rice growth are solved. [0003] When rice is transplanted or in the early stage of dry-seeded rice growth, the growth of rice will be affected by the lack of sufficient nitrogen, phosphorus, and potassium. At the same t...

Problems solved by technology

[0002] Fertilizers and fertilization are very important in agricultural production. Chemical fertilizers account for 30%-40% of the increase in crop production. At present, ordinary compound fertilizers are generally used as base fertilizers in the early stage of rice transplanting or direct-seeding rice, but ordinary compound fertilizers cannot Effectively solve the problems of long slow seedling period of rice when transplanting, yellow and thin, and multiple stiff seedlings in the early stage of dry direct seeding rice growth

[0003] When rice is transplanted or in the early stage of dry-seeded rice growth, the growth of rice will be affected by the lack of sufficient nitrogen, phosphorus, and potassium. At the same time, the lack of medium and trace elements such as silicon and zinc will also affect the normal growth of rice. In particular, the occurrence of tillering has adverse effects; rice is a silicon-loving crop and is very sensitive to silicon, which is an important element for building cell walls. If the available silicon in the soil is insufficient, it may cause rice plants to be weak and prone to lodging. Significant decline in disease performance

When rice is transplanted, it usually causes great damage to its root system, and the vitality of the root system decreases, resulting in the common phenomenon of stiff seedlings and yellow seedlings. Generally, the slow seedling period of rice seedlings reaches 3-4 days. The barley is late, the slow seedling stage is prolonged, and the tillering occurs later, which will affect the improvement of rice yield and quality
