In the process of cultivation, farmers' friends always think that using micro-fertilizers for crops can produce high yields. In fact, the authors have learned through relevant experts that trace element fertilizers are developed according to the needs of different crops or crops in different growth stages. Micro-fertilizer must be used in a targeted manner to receive good results. The following is an introduction to the efficient use of commonly used micro-fertilizers as follows:
Selection of soaking seeds (seed dressing) micro-fertilizer and preparation of micro-fertilizer for soaking seeds, first dissolve the micro-fertilizer into a certain concentration of aqueous solution, and then soak the seeds, then borrow the physiological function of the water-swelling of the seeds to inhale the trace elements into the seeds. In the body, it can be sown after drying. It is often used as a micro-fertilizer for soaking seeds and is used in the following ways: 1. Zinc soaking seeds. When the seed is soaked with zinc fertilizer, the concentration is 0.02%-0.05%, which is subject to uniform seed soaking; the concentration for rice soaking is 0.1%, and the soaking time is 24 hours. It is advisable to mix 2 g to 6 g of zinc fertilizer per kg of seed during seed dressing. 2. Molybdenum fertilizer soaking seeds. When seed dressing, 1 g to 2 g of molybdenum fertilizer can be used per kilogram of seed, and the mixture is evenly mixed; the concentration during soaking is 0.05% to 0.1%, and soaking for 12 hours. 3. Manganese fertilizer soaking. When seed dressing, 2 grams to 4 grams of manganese fertilizer can be used per kilogram of seed; the concentration of soaking seeds is 0.05% to 0.1%. 4. Copper fertilizer soaking. When seed dressing, 0.6 g to 1.2 g of copper fertilizer can be used per kg of seed; the soaking concentration is preferably 0.01% to 0.05%.
Selection of micro-fertilizer for micro-fertilization The method of soaking roots for micro-fertilizer is to dissolve the micro-fertilizer into a certain concentration of aqueous solution, and then soak the roots of the crop plant to allow trace elements to enter the plant body through the profile. Boron fertilizer is a commonly used micro-fertilizer for immersion, and the concentration at the time of immersion is preferably 0.01% to 0.1%.
Used as a base fertilizer Micro-fertilizer is an indispensable element for crop growth. When the micro-fertilizer is used as the base fertilizer, a certain micro-fertilizer can be mixed with the fine dry soil (or fine slag fertilizer), and combined with the tillage and land preparation before the crop is planted. When the zinc fertilizer is used as the base fertilizer, the dosage per acre is 1 kg to 2.5 kg; when the manganese fertilizer is used as the base fertilizer, the dosage per mu is 1 kg to 2 kg. It should be noted that since the micro-fertilizer is generally used in a small amount, it should not be applied in depth when used, and should be used in a timely and appropriate amount according to the fertilizer characteristics of the crop.
Used as a top dressing Mixing micro-fertilizer with fine soil or adding water proportionally, and applying it to the soil during the crop growth period. When used in paddy fields, it can be mixed with fine soil and then applied (or poured after watering); when applied in dry land, it is usually added to dry manure (or manure water) for application, ditch application and strip application. When zinc fertilizer is used as top dressing, the dosage per acre is preferably from 1 kg to 1.2 kg.
Selection of foliar application of micro-fertilizer The most common method of micro-fertilizer is to prepare a certain concentration of solution with water for foliar application. The foliar spray concentration of zinc fertilizer is 0.1%-0.2%, the dosage per acre (syrup) is about 25 kg-50 kg; the foliar spray concentration of molybdenum fertilizer is 0.05%-0.1%; the foliar spray of manganese fertilizer The concentration of application is 0.05%-0.1% (30 liters to 50 liters per liter of syrup); the foliar application concentration of iron fertilizer is 0.2% to 1%; the foliar application concentration of copper fertilizer (copper sulfate solution) 0.02 to 0.05% is preferred. It should be noted that the water added by spraying the micro-fertilizer should be clean and should be thoroughly stirred. Spraying time should be selected when there is no dew. Because there is dew when the fertilizer is not easy to adhere to the foliage of the crop and it is easy to be diluted, it should not be sprayed at hot noon. Because of the strong sunlight at noon, it evaporates quickly and easily causes burns. And unfavorable absorption. Therefore, the best time for spraying micro-fertilizer should be after 4 pm, when the temperature drops, the leaves of the crop are dry, the fertilizer liquid is easy to adhere, and after one night, the nutrients of the micro-fertilizer can be fully Crop absorption.
Selection of soaking seeds (seed dressing) micro-fertilizer and preparation of micro-fertilizer for soaking seeds, first dissolve the micro-fertilizer into a certain concentration of aqueous solution, and then soak the seeds, then borrow the physiological function of the water-swelling of the seeds to inhale the trace elements into the seeds.
