Embodiment 1

[0028] A. Mix one or more of poultry manure and crop stalks, dry and granulate after high-temperature aerobic fermentation, and make organic fertilizer for later use;

[0029] B, get standby organic fertilizer 20kg, urea 50kg, potassium dihydrogen phosphate 50kg and filler (this embodiment adopts kaolin as filler, also can adopt other filler) 10kg to pulverize respectively, then add plant growth regulator (this Embodiment adopts compound sodium nitrophenolate, also can adopt other plant growth regulator) 0.04kg, after mechanically mixing together, sub-package is divided into the small package of every bag 2kg, becomes paddy rice seedling fertilizer.

[0030] The rice seedling raising fertilizer of the present invention is suitable for the soil in southern my country, and when used, adopts different methods according to different seedling raising methods:

[0031] (1), paddy field seedling field: under the situation that seedling field divides good compartment, on the required ...

Embodiment 2

[0035] A. Mix one or more of poultry manure and crop stalks, dry and granulate after high-temperature aerobic fermentation, and make organic fertilizer for later use;

[0036] B, get standby organic fertilizer 50kg, urea 20kg, potassium dihydrogen phosphate 20kg and filler (this embodiment adopts kaolin as filler, also can adopt other filler) 5kg to pulverize respectively, then add plant growth regulator (this The embodiment adopts compound sodium nitrophenolate, also can adopt other plant growth regulator) 0.02kg, after mechanical mixing together, sub-package is divided into the small package of every bag 2kg, becomes paddy rice seedling fertilizer.

Abstract

The invention discloses a rice seedling fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizer production. The rice seedling fertilizer is prepared from the following components in parts by weight: 20-50 parts of organic fertilizer, 20-50 parts of urea, 20-50 parts of potassium dihydrogen phosphate, 5-10 parts of filling material and 0.02-0.06 part of plant growth regulator. The preparation method comprises the following steps of: firstly, mixing one or more than one of livestock manure and crop straws, aerobically fermenting at high temperature, drying and granulating to prepare the organic fertilizer for standby use; and respectively pulverizing the standby organic fertilizer, the urea, the potassium dihydrogen phosphate and the filling material, adding a plant growth regulator, mechanically and uniformly mixing, and packaging to obtain the rice seedling fertilizer. The rice seedling fertilizer has the characteristics of high contentof organic matters and quick-acting nitrogen and potassium, high seedling resistance, strong seedlings, applicability to south soil and the like. The rice seedling fertilizer is applicable to rice seedling cultivation throughout the South of china.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to rice seedling raising fertilizer and a preparation method thereof. Background technique [0002] "Seedlings are good for half-field grains", this is farmers' understanding of the importance of rice seedling cultivation, and the key to rice seedling cultivation is how to use fertilizer, what kind of fertilizer to use, and when to use fertilizer. If used properly, strong seedlings can be cultivated, thereby laying a solid foundation for high and stable yields in the field. At present, there is no special fertilizer for rice seedlings on the market. Therefore, when rice seedlings are raised in southern rural areas, nitrogen fertilizers are usually used as the main fertilizer. Because the organic matter and available potassium content of southern rice fields are generally low, early rice seedlings often have weak cold resistance. The seedlings are delicate...
