Embodiment 1

[0037] Each component is weighed according to the following ratio of parts by weight: 16 parts of polyvinyl alcohol, 6 parts of starch, 3 parts of tripterine, 30 parts of plant ash, 5 parts of nitrate nitrogen fertilizer, and 35 parts of water.

[0038] Add part of water to polyvinyl alcohol to make polyvinyl alcohol aqueous solution as component one. Then add remaining water to the starch, and ripen at 80° C. for 30 minutes to obtain component 2. Mix component 1, component 2, triptolide, nitrate nitrogen fertilizer, and plant ash evenly.

[0039] When in use, the prepared slow-release fertilizer can be directly used as a base fertilizer for corn; it can also be dried and crushed to obtain granular slow-release fertilizer, which can be used as a base fertilizer for corn.

[0040] Experiment was carried out with 100 mu of corn in a certain place in Sichuan, and 85 kg of the slow-release fertilizer of this embodiment was applied per mu. It has been determined that the yield of...

Embodiment 2

[0042] Each component is weighed according to the following ratio of parts by weight: 22 parts of polyvinyl alcohol, 8 parts of starch, 5 parts of tripterine, 25 parts of plant ash, 8 parts of nitrate nitrogen fertilizer, and 55 parts of water.

[0043] Add part of water to polyvinyl alcohol to make polyvinyl alcohol aqueous solution as component one. Then add the remaining water to the starch, and ripen it at 85° C. for 35 minutes to obtain component 2. Mix component 1, component 2, triptolide, nitrate nitrogen fertilizer, and plant ash evenly.

[0044] When in use, the prepared slow-release fertilizer can be directly used as a base fertilizer for corn; it can also be dried and crushed to obtain granular slow-release fertilizer, which can be used as a base fertilizer for corn.

[0045] Experiment was carried out with 50 mu of corn in a certain place in Sichuan, and 80 kg of the slow-release fertilizer of this embodiment was applied per mu. It has been determined that the yi...

Embodiment 3

[0047] Each component is weighed according to the following ratio of parts by weight: 15 parts of polyvinyl alcohol, 5 parts of starch, 5 parts of tripterine, 22 parts of plant ash, 6 parts of nitrate nitrogen fertilizer, and 27 parts of water.

[0048] Add part of water to polyvinyl alcohol to make polyvinyl alcohol aqueous solution as component one. Then add remaining water to the starch, and ripen it at 60° C. for 60 minutes to obtain component 2. Mix component 1, component 2, triptolide, nitrate nitrogen fertilizer, and plant ash evenly.

[0049] When in use, the prepared slow-release fertilizer can be directly used as a base fertilizer for corn; it can also be dried and crushed to obtain granular slow-release fertilizer, which can be used as a base fertilizer for corn.

[0050] Experiment was carried out with 120 mu of corn in a certain place in Sichuan, and 90 kg of the slow-release fertilizer of this embodiment was applied per mu. It has been determined that the yield...

Abstract

The invention discloses a slow-release fertilizer for corn and a preparation method thereof. The objective of the invention is to overcome the problems of waste of fertilizer and necrosis of part of leaves in conventional foliar fertilization manner for corn and the problems of insufficient supply of fertilizer and influence on normal growth of corn due to human factors in the prior art. The slow-release fertilizer comprises, by weight, 15 to 25 parts of polyvinyl alcohol, 5 to 8 parts of starch, 2 to 5 parts of wilfordine, 20 to 35 parts of plant ash, 5 to 10 parts of nitrate nitrogen fertilizer and 20 to 80 parts of water. The slow-release fertilizer for corn provided by the invention makes a breakthrough to conventions; and when the slow-release fertilizer is used as a base fertilizer, needs of corn in growth are met through slow release of the slow-release fertilizer, and continuous and long-acting supply of nutrients to corn is realized. During growth of core, needs of corn for water and nutrients can be met only by watering; and since foliar fertilization is not needed for corn, necrosis of part of leaves is prevented, waste of the fertilizer is effectively lowered, cost for the fertilizer can be saved, and investment for agricultural production is reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to the field of agricultural fertilizers, in particular to a slow-release fertilizer for corn and a preparation method thereof. Background technique [0002] Corn, also known as corn, celestial wheat, corn, corn, corn, cob, corn corn, is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world, compared with rice. The output is even higher. [0003] The mesophyll cells of maize are differentiated into two types, one type is loosely dispersed in the leaves, while the other type is tightly surrounded around the veins. In those loose mesophyll cells that are in direct contact with the air, carbon dioxide is fixed by an enzyme called phosphoenolpyruvate carboxylase (PEPC), which has a strong affinity for carbon dioxide, whereas the initial The carbon fixation product is a molecule with 4 carbon atom...
