Rice root striking medical fertilizer and application thereof

Abstract

The invention discloses a rice root striking medical fertilizer and application thereof. The rice root striking medical fertilizer is composed of raw materials including, by weight percentage, 5%-40%of organic matters, 5%-60% of major elements, 0.5%-20% of medium elements, 0.5%-20% of micro elements, 0.5%-5% of silicon fertilizer and 0.1%-10% of plant growth regulator, wherein the plant growth regulator comprises compound sodium nitrophenolate. The invention also discloses application of the rice root striking medical fertilizer to rice root striking. The rice root striking medical fertilizercan reduce soil and water pollution as well as soil hardening in fields after being applied; the added organic matters can improve the soil fertility by exciting activity of microorganisms; the applied amount of phosphate fertilizer, potassium fertilizer, zinc fertilizer and silicon fertilizer is moderately increased to promote metabolism of nutrients in rice plants and enhance rice growth; effective silicon can promote decomposition of the organic matters and formation of granular structures in soil to enhance breathability of the rice plants and growth of root systems and meanwhile to prevent rotting and premature of the root systems. Besides, the rice root striking medical fertilizer is green and environmentally friendly and has no adverse influence on soil and environment.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a rice rejuvenation medicinal fertilizer and its application. Background technique [0002] Rice is a kind of herbaceous rice. It likes high temperature, high humidity, and short day. It does not have strict requirements on the soil. Paddy soil is the best. Rice is a fibrous root system, with developed adventitious roots, panicles, and self-pollination. It is an annual cultivated grain. The stalk is upright, 30-100 cm high. Leaves alternate in two rows, linear-lanceolate, ligule membranous, 2-lobed. The panicles are loose; the spikelets are oblong, squashed on both sides, containing 3 small flowers, the glumes are degenerate, leaving only traces, the apical florets are bisexual, lemma boat-shaped, with awn; stamens 6; 2 degraded flowers leaving only lemmas located Under bisexual flowers, they are often mistaken for glumes and caryopsis. [0003] Rice is mainly grown in the thre...

Problems solved by technology

[0010] Cultivation is unreasonable: Some rice ponds have a height difference of more than 5 cm. When watering, the high part is exposed to the land, and the water in the depression is very deep. Because the harrowed field is very fine, when transplanting seedlings, the soil particles formed on the soil surface are very small (less than 0.01 mm) soil layer, because the soil particles are small and have poor water permeability and air permeability, the oxygen content in the soil is reduced, the root system undergoes anaerobic respiration, and the root system vitality decreases, which is not conducive to root system development, slow rooting, short root system, and few white roots. Form black roots, turn green slowly

[0011] Improper dosage can easily lead to excessive growth of rice and unhealthy plants, which can easily lead to the occurrence of diseases and insect pests in the middle and late stages. At the same time, the long-term excessive topdressing of sulfur-based or chlorine-based fertilizers can also cause soil compaction and pollution to the agricultural environment.
