Fertilizer special for high-potassium rice and preparation method of fertilizer

Abstract

The invention relates to a fertilizer special for high-potassium rice and a preparation method of the fertilizer. The special fertilizer is prepared by mixing potassium sulfate, monopotassium phosphate, anhydrous magnesium sulfate, sodium octaborate tetrahydrate, zinc sulfate, ferrous sulfate, ethylene diamine tetraacetate (EDTA) copper, EDTA manganese, ammonium molybdate, citric acid, sodium citrate, EDTA-2 sodium and sodium tripolyphosphate in a ratio. The fertilizer special for the high-potassium rice can meet the requirement of the rice on the potassium fertilizer and provide balanced trace elements such as ferrum, zinc, boron and the like which have the important effect on the yield of the rice, and particularly can be used flexibly in the middle and late period of the rice; and the fertilizer is easy to absorb by the rice, so that the rice has balanced and sufficient nutrient, and the yield and quality of the rice can be improved obviously. Particularly, the fertilizer is used in seed production fields of the rice, the seed production quality of the rice is improved, the flower synchronization of male parent flowers and female parent flowers is promoted, and the disease infection due to potassium deficiency can be prevented, so that the yield of rice seeds is improved, the standard of seed quarantine is met, and seeds are full, high in quality and reliable.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a special fertilizer for high-potassium rice and a preparation method thereof. Background technique [0002] At present, rice fertilization is mostly based on conventional elemental fertilizers such as urea, ammonium bicarbonate, ammonium phosphate, and potassium chloride. There are some problems in such a fertilizer habit, which has brought serious nitrogen partial application and insufficient nutrient supply to rice production. A matter of balance. It cannot meet the demand for potassium and trace elements in the rice production process. Such as too much nitrogen fertilizer, the rice seedlings will be green and late-maturing, the vegetative growth period will be prolonged, the reproductive growth will be delayed, they will not mature normally, they will easily lodging, and it will easily cause various diseases such as rice blast. The imbalance of fertilizer in...

Can not meet the demand for potassium and trace elements in the rice production process

Such as too much nitrogen fertilizer, the rice seedlings will be green and late-maturing, the vegetative growth period will be prolonged, the reproductive growth will be delayed, they will not mature normally, they will easily lodging, and it will easily cause various diseases such as rice blast. The imbalance of fertilizer inhibits the absorption of zinc by rice and affects the normal growth of rice, especially the growth of rice seedlings and before tillering

At present, farmers pay far less attention to potassium fertilizer than nitrogen fertilizer. On the one hand, it is related to the farmers' farming level, and on the other hand, it is related to the lack of alternative high-quality rice fertilizers in production.

In addition, the potassium fertilizer currently used in rice production is usually easily lost, and it is difficult to effectively meet the growth needs of rice at the earing stage.
