Problems solved by technology

The development status of high-concentration, one-time application of general-purpose compound fertilizers has caused many problems, such as a large accumulation of soil nutrients and high fertilizer prices.
[0003] At present, the compound fertilizers sold on the market are generally three elements (nitrogen, phosphorus, potassium) compound fertilizers, and there is no special resistance factor to rice lodging. In the process of hybrid rice (Xiangzaoyou 2017) seed production, female parent phimosis must be solved The problem is that a large dose of gibberellin (920) must be applied, which will inevitably elongate the main trunk of the plant and reduce the lodging resistance of the plant. Lodging will lead to a substantial reduction in yield. Therefore, there is an urgent need for a special fertilizer for hybrid rice lodging resistance. Increase rice yield

Embodiment 1

[0026] Example 1. A special lodging-resistant fertilizer for hybrid rice seed production, including original fertilizer, including 47.1 kg of ammonium chloride with a nitrogen content of 17%, 17.8 kg of calcium superphosphate with a phosphorus content of 45%, and a potassium content of 60%. 13.3kg of potassium chloride, 1.3kg of silicon fertilizer with 80% silicon content and 20.5kg of filler. The filler is pyrophyllite powder or pyrophyllite granules.

[0027] The preparation method of the lodging resistance special fertilizer for hybrid rice seed production is prepared according to the following steps;

[0028] Mix the raw materials in the ratio to obtain product A; then add 8ml of water to stir and mix to obtain product B; after the product B is agglomerated, grind it to obtain a powder, and then granulate and dry it to obtain finished product. The granulation is a conventional granulation method. The present invention is mainly aimed at the seed production of Xiangzaoy...

Embodiment 2

[0029] Example 2. A kind of anti-lodging special fertilizer for hybrid rice seed production, including original fertilizer, including 43kg of ammonium chloride with a nitrogen content of 17%, 16kg of superphosphate with a phosphorus content of 45%, and chlorine with a potassium content of 60%. 13kg of potassium chloride, 1.3kg of silicon fertilizer with 80% silicon content and 20.3kg of filler. The filler is pyrophyllite powder or pyrophyllite granules. All the other are with embodiment 1.

Embodiment 3

[0030] Example 3. A kind of anti-lodging special fertilizer for hybrid rice seed production, including original fertilizer, including 48kg of ammonium chloride with a nitrogen content of 17%, 18kg of superphosphate with a phosphorus content of 45%, and chlorine dioxide with a potassium content of 60%. 11kg of potassium chloride, 1.4kg of silicon fertilizer with 80% silicon content and 20.8kg of filler. The filler is pyrophyllite powder or pyrophyllite granules. All the other are with embodiment 1.

Abstract

The invention discloses a hybrid rice seed production lodging resistant special fertilizer and a preparation method thereof. The special fertilizer comprises an original fertilizer, which includes, by mass, 38-52 parts of ammonium chloride with a nitrogen content of 17%, 12-22 parts of calcium superphosphate with a phosphorus content of 45%, 8-18 parts of potassium chloride with a potassium content of 60%, 1-2 parts of a silicon fertilizer with a silicon content of 80%, and 18-23 parts of filler. The special fertilizer provided by the invention can effectively strengthen the lodging-resistance capability of rice seed production, and also improves the yield.

Description

technical field [0001] The invention relates to a special fertilizer for hybrid rice and a preparation method thereof, in particular to a special fertilizer for lodging resistance in hybrid rice seed production and a preparation method thereof. Background technique [0002] The last 10 years is the stage of the fastest development of my country's chemical fertilizer industry. The total amount of chemical fertilizers has grown rapidly. The self-sufficiency rate of nitrogen and phosphate fertilizers has exceeded 100%, and the proportion of high-concentration nitrogen fertilizers and phosphate fertilizers has exceeded 50%. develop. In 2005, my country's compound fertilizer output reached 1.35 million tons P 2 o 5 , accounting for 8% of the total phosphate fertilizer output and 27% of the total chemical fertilizer consumption; in 2007, my country's compound fertilizer output reached 1.96 million tons of P 2 o 5 , accounting for 14.5% of the total phosphate fertilizer output...
