[0020] 1. Distribution of nitrogen, phosphorus and potassium fertilizers at each stage of corn cultivation and growth:

[0021] Seed fertilizer nitrogen 40%, seed fertilizer phosphorus 100%, seed fertilizer potassium 80%, topdressing nitrogen 60% at the eight-leaf stage, or ten-leaf stage at the twelve-leaf stage, and topdressing potassium 20%.

[0022] The dosage form of seed fertilizer is: urea, zinc-containing ammonium sulfate (N19-Zn3), monoammonium phosphate (11-44-0), diammonium phosphate (16-44-0), potassium chloride (0-0-60) . P provided by monoammonium phosphate and diammonium phosphate 2 o 5 50% and 50%, while providing corresponding nitrogen, the remaining nitrogen comes from urea and zinc-containing ammonium sulfate, and the ratio of nitrogen provided by the two is 70...

Embodiment 2

[0028] The difference between this embodiment and embodiment 1 is:

[0029] For areas with an effective accumulated temperature ≥10°C of 2600-3000°C, apply total nitrogen 170kgha -1 , total phosphorus 80kgha -1 , Potassium 110kgha -1 , of which seed fertilizer: nitrogen 68kgha -1 , Phosphorus 80kgha -1 , Potassium 88kgha -1 , Topdressing at the 12-leaf stage: nitrogen 108kgha -1 , Potassium 22kgha -1 .

[0030] For areas with an effective accumulated temperature ≥10°C of 2200-2600°C, apply 150kgha of total nitrogen -1 , total phosphorus 75kgha -1 , Potassium 100kgha -1 , of which seed fertilizer: nitrogen 60kgha -1 , Phosphorus 75kgha -1 , Potassium 80kgha -1 , topdressing at the ten-leaf stage: nitrogen 90kgha -1 , Potassium 20kgha -1 .

[0031] In areas where the effective accumulated temperature of ≥10°C is less than 2200°C, the application of total nitrogen is 130kgha -1 , total phosphorus 70kgha -1 , Potassium 80kgha -1 ; Seed fertilizer: nitrogen 42kgha...

Embodiment 3

[0033] The difference between this embodiment and embodiment 1 is:

[0034] For areas with an effective accumulated temperature ≥10°C of 2600-3000°C, the application of total nitrogen is 165kgha -1 , total phosphorus 70kgha -1 , Potassium 105kgha -1 , of which seed fertilizer: nitrogen 66kgha -1 , Phosphorus 70kgha -1 , Potassium 84kgha -1 , Topdressing at the 12-leaf stage: nitrogen 99kgha -1 , Potassium 21kgha -1 .

[0035] For areas with an effective accumulated temperature ≥10°C of 2200-2600°C, apply 140kgha of total nitrogen -1 , total phosphorus 65kgha -1 , Potassium 90kgha -1 , of which seed fertilizer: nitrogen 56kgha -1 , Phosphorus 65kgha -1 , Potassium 72kgha -1 , topdressing at the ten-leaf stage: nitrogen 84kgha -1 , Potassium 18kgha -1 .

[0036] In areas where the effective accumulated temperature of ≥10°C is less than 2200°C, 120kgha of total nitrogen should be applied -1 , total phosphorus 60kgha -1 , Potassium 75kgha -1 ; Seed fertilizer: ni...

Abstract

The invention discloses an agricultural machine and agricultural technology integrated fertilizer application method for increasing the yield and the quality of corns in cold areas. The fertilizer application method comprises the following steps of applying a seed fertilizer at the depth of 10-15cm on a position 6-8cm away from a seedling side by using a technology for deeply applying a fertilizer at a machine side, carrying out additional fertilization at the depth of 15-20cm between two rows of seedlings in a big-ridge double-row cultivation mode; and carrying out additional fertilization at the depth of 15-20cm at a ridge side 15-20cm away from the seedling side in a small ridge cultivation mode. The dosages of nitrogen, phosphorus and potassium at all cultivation and growth stages of corns under the condition that the total dosage of pure nitrogen, phosphorus and potassium is definite are distributed as follows: pure nitrogen in the applied seed fertilizer accounts for 30-40% of the total nitrogen content, pure phosphorus in the applied seed fertilizer accounts for 100% of the total phosphorus content (P2O5), pure potassium in the applied seed fertilizer accounts for 70-80% of the total potassium content, pure nitrogen for additional fertilization accounts for 60-70% of the total nitrogen content, and pure potassium for additional fertilization accounts for 20-30% of the total potassium content. By using the fertilizer application method, the fertilizer application period is consistent with the fertilizer requirement law of the corns, meanwhile, the dosage forms of nitrogen fertilizer and phosphate fertilizer are regulated, the colony in the vegetative period of the corns is kept not over-productive, the colony quality of the corns is improved, the nutrient requirements of the corns can be met at the late growth stage, and the root activity of the corns can be improved.

Description

technical field [0001] The invention relates to a corn fertilization method. Background technique [0002] Corn is a major industrial raw material, feed and food crop. In 2014, the planting area of ​​corn in Heilongjiang Province has exceeded 100 million mu, and there is a trend of further development. Corn production is closely related to my country's food security issues. Continuous improvement of corn fertilization technology is the main way to protect the fertility of black soil and increase and stabilize rice production. It is a key issue for sustainable agricultural development and an important guarantee for food security. [0003] The problems existing in the traditional corn fertilization technology mainly include: the total amount of fertilization is high, the distribution ratio of nitrogen, phosphorus and potassium is unreasonable, and the proportion of nitrogen is too high. Generally, the nitrogen input of seed fertilizer in the early stage of corn production exce...
