Maize seed fertilizer selection and fertilization method

First, how to use corn seed fertilizer

1, seed dressing: You can use humic acid, biological fertilizer and micro-fertilizer, the fertilizer is dissolved, sprayed on the corn seed, while spraying and mixing, so that the fertilizer solution evenly stained on the seed surface, dry after sowing.

2, soaking: The fertilizer is dissolved to a certain concentration, the seeds are soaked in the solution for 12 hours, sowing immediately after drying.

3, Article Shi or acupuncture: chemical fertilizer suitable for application or acupuncture points, the amount of 2 to 5 kg, but the fertilizer must be separated from the seed, deeper and better fertilization, the depth of 10 to 15 cm is appropriate, urea, ammonium bicarbonate Ammonium chloride, potassium chloride should not be used as seed fertilizer.

Second, the benefits of applying corn seed fertilizer

The application of corn seed fertilizer is mainly to meet the needs of nutrients in the early growth stage of corn, and is mainly used in the land where insufficient amount of base fertilizer is used. Fertilizers are mainly available nitrogen and phosphorus fertilizers. Spring maize in high-cold areas has low soil temperature and slow release of available phosphorus, and is prone to phosphorus deficiency. If a high-quality, decomposed organic fertilizer and phosphate fertilizer are used as seed fertilizers, the effect will be better. The basal fertilizer does not have a field of zinc fertilizer applied. It can be used for seed dressing with zinc fertilizer. Mix 6-8 grams of zinc sulfate per kilogram of seed. When fertilizing fertilizer, the amount should not be too large, so as not to affect the seed germination. Fertilizers should be applied next to the seeds. The seeds can be applied 4-5 centimeters from the seeds.

Third, how to choose corn seed fertilizer

1. Fertilizer fertilizers such as potassium chloride and ammonium chloride contain chloride ions. When applied to the soil, they will produce water-soluble chlorides, which are harmful to seed germination and seedling growth, and may even be burned and burned. Ammonium nitrate, potassium nitrate, etc. Fertilizers contain nitrate ions and have toxic effects on seed germination; Ammonium bicarbonate is volatile and corrosive, easily smoked seeds and seedlings; Urea produces a small amount of biuret, if the content exceeds 2%, it will produce seeds and seedlings. Poisoning. These are not suitable for seed fertilizer, otherwise it is easy to burn buds, burn seedlings, nitrogen, phosphorus, potassium compound fertilizer can be applied or controlled release fertilizer.

2, control the amount of fertilizer required corn seedlings less, in order to reduce waste, fertilizer application amount should not be too large, generally about 10 kg per acre, especially when sowing, it is necessary to strictly control the amount of seed fertilizer application.

3, do a good job in seed fertilizer isolation application of seed fertilizer, in order to avoid direct contact with the seed and fertilizer lead to burning buds, burning seedlings, mechanical seeding to isolate the seed and fertilizer 7 to 10 cm; artificial seeding, to change the fertilizer under the side Deep application or deep interspecies facilities.
