Seaweed rice seedbed conditioner and preparation method thereof

Abstract

The invention discloses a seaweed rice seedbed conditioner and a preparation method thereof. The conditioner is prepared from the following raw material components in parts by weight: 80-150 parts ofcomposted enteromorpha, 8-12 parts of oyster powder, 500-600 parts of ammonium sulfate, 120-160 parts of monoammonium phosphate, 40-60 parts of potassium sulfate, 60-100 parts of sulfonated humic acid, 4-8 parts of zinc sulfate monohydrate, 4-8 parts of manganese sulfate monohydrate, 1-2 parts of a microbial agent, 8-12 parts of ferrous sulfate and 0.8-1.2 parts of paclobutrazol. According to theinvention, the composted enteromorpha and the oyster powder are added into the conditioner, so that the soil fertility can be improved, the soil structure can be improved, the nutrient absorption canbe promoted, and the disease resistance and stress resistance of crops can be enhanced; the microbial agent increases crop nutrition, stimulates and regulates crop growth, reduces or reduces plant diseases and insect pests, and improves the seedling rate; and the conditioner disclosed by the invention is added into a rice seedbed to be used for raising seedlings, so that the aims of nutrition long-acting absorption, root promotion, dwarf and strong growth, tillering increase, stress resistance enhancement, disease reduction, seedling rate increase, comprehensive seedling quality improvement and yield and income increase can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a seaweed rice seedbed conditioner and a preparation method thereof. [0002] technical background [0003] Rice is a traditional crop in my country, and it is also the main variety of my country's grain production. It plays an important role in agricultural production. In 2016, among the 10 countries with the largest rice planting area in the world, my country's per unit yield level was the highest, reaching 462.5 kg / 667m2. With the rapid development of my country's economy and the acceleration of urbanization, my country's agriculture is still facing the contradiction between the rigid growth of food demand and the shortage of arable land, water and other resources, the contradiction between the balance of food supply and demand and structural shortage, and the rising cost of agricultural production. The contradiction of declining economic benefits. The...

Problems solved by technology

[0006] For the rice seedbed conditioner in the prior art, it is easy to make the seedling grow vigorously, the resistance becomes poor, and the excessive inorganic fertilizer makes the soil fertility decrease when it is used. The purpose of the present invention is to provide a seaweed rice seedbed conditioner and its preparation method. The rice seedbed conditioner product prepared by the present invention is added to the rice seedbed to grow seedlings, which can achieve long-term absorption of nutrients, promote root growth, shortness, increase tillering, enhance stress resistance, reduce diseases, increase seedling growth rate, and comprehensively The purpose of improving the quality of seedlings
