Micro-fertilizer applied to vegetables to pay attention to the dose

The reason why it is called micro-fertilizer is because its demand is small and the amount is small, but it is not enough to lack this element. However, many vegetable farmers are not very familiar with the amount of micronutrient fertilizers. Some vegetable farmers, like compound fertilizers, use a few tens of pounds to over a hundred pounds at a time. This not only causes serious waste, but also causes poisoning to vegetables. The following describes the use of several major fertilizers dose:

1. Boron fertilizer. There are borax, boric acid, followed by boron and magnesium fertilizer. Borax and boric acid are commonly used boron fertilizers. Each acre of soil application or topdressing 0.5 to 0.75 kg, foliar spray concentration of 0.1% to 0.3%, soaking concentration of 0.01% to 0.1%, seed dressing per kg of seed fertilizer 0.2 ~ 0.5 grams.

2. Zinc fertilizer. There are mainly zinc sulfate, zinc oxide, zinc nitride, and chelated zinc. Zinc sulphate is commonly used zinc fertilizer, soil application or topdressing 1 to 2 kilograms per acre, foliar spray concentration of 0.01% to 0.05%, soaking concentration of 0.02% to 0.05%, seed dressing per kilogram of seed fertilizer 1 to 3 Grams.

3. Mo fertilizer. There are mainly ammonium molybdate, followed by sodium molybdate and molybdenum trioxide. Ammonium molybdate is a commonly used molybdenum fertilizer, applying or applying 50-150 g per acre of soil at the end, spraying a concentration of 0.01%-0.1%, soaking in a concentration of 0.05%-0.1%, and dressing seed for a fertilizer of 2-5 per kilogram of seed. Grams.

4. Copper fertilizer. There are mainly copper sulfate, copper oxide, chelated copper, and copper-containing slag. Copper sulphate is commonly used copper fertilizer, applying 0.8-1.5 kilograms per acre of soil or topdressing, foliar spray concentration of 0.01%-0.05%, soaking concentration of 0.01%-0.05%, and seed dressing of 0.3 grams per kilogram of seed fertilizer.

5. Manganese fertilizer. Mainly manganese sulfate, followed by manganese carbonate, manganese chloride, manganese oxide and so on. Manganese sulphate is a commonly used manganese fertilizer, applied or applied 1 to 2 kilograms per acre soil, foliar spray concentration of 0.05% to 0.2%, soaking concentration of 0.05% to 0.1%, seed dressing per kilogram of seed fertilizer 4 ~ 8 grams.

6. Iron fertilizer. There are mainly ferrous sulfate, in addition to ferrous ammonium sulfate, iron chelates. Ferrous sulphate is a commonly used species. Each kilogram of soil applied or topdressing 5 kilograms, foliar spray concentration of 0.3% to 0.5%.

The amount of micro-fertilizer is very small, and how to apply it evenly is a problem that plagues many vegetable farmers. A vegetable farmer felt that the fertilizer was too little and could not be used at all. Therefore, he did not use or increased the amount of micro fertilizer, which was not good for the normal growth of vegetables. In fact, the uniform application of micronutrients is also very simple, because most of the micronutrients are soluble. The vegetable growers can spray the dissolved fertilizer on the ground after the base fertilizer is spread, and plow together with the base fertilizer into the soil; or The fertilizer is dissolved in a bucket and flushed with water during watering.
