  • Which crops can paraquat be used on? Detailed introduction to its scope of application

    Which crops can paraquat be used on? Please give a detailed introduction. Paraquat is a fast-acting non-selective herbicide with contact action and a certain systemic action. It is rapidly absorbed by the green tissues of plants, causing them to wither and die. It has no effect on non-green tissues. In soil it rapidly binds to soil particles and becomes deactivated, with no effect on plant roots and many...

  • Correct application methods for ammonium-nitrogen compound fertilizer

    How should ammonium-nitrogen compound fertilizer be applied? Please give an introduction. There are three types of nitrogen fertilizer in compound fertilizer: ammonium nitrogen, nitrate nitrogen and urea. Nitrate nitrogen is absorbed most quickly by crops, but it is not easily retained in the soil and is prone to leaching with water, so it is best used as a top dressing and less suitable as a base fertilizer; urea also leaches easily, and after being applied to the soil it must undergo transformation before it can be absorbed by crops. This process takes a long time when spring soil temperatures are low, and its effect is too slow, so it is also not ideal as a base fertilizer. Only ammonium nitrogen is both easily adsorbed and retained by the soil, not prone to leaching, and unaffected by low temperatures, giving it the highest utilization rate and making it the most ideal base fertilizer. Therefore, ammonium-nitrogen compound fertilizer is suitable for application as a base fertilizer.

  • How to use flush fertilization well? You need to master the correct application methods

    How do you use flush fertilization well? Please give an introduction. First, correctly choose the type of fertilizer for flush fertilization. Only water-soluble fertilizers can be applied with water. Among nitrogen fertilizers, urea, ammonia water, ammonium sulfate and ammonium nitrate are commonly used; among potassium fertilizers, there are potassium chloride and potassium sulfate, and potassium nitrate can also be used. Among phosphorus fertilizers, even if they are water-soluble monoammonium phosphate and phos...

    How is acetochlor applied? Please explain. Acetochlor is also known as Harness and acetochlor. It is suitable for soybeans, oil crops, peanuts, corn, cotton, vegetables, etc. It controls annual grass weeds and some broadleaf weeds. It is ineffective against perennial weeds. Acetochlor is a pre-emergence soil treatment, applied before crop emergence around sowing time...

  • Which crops are suitable for potassium sulfate and potassium chloride application?

    Which crops are suitable for potassium sulfate or potassium chloride application? Please give an introduction. Crop chloride tolerance refers to a crop's ability to endure chloride applied to the roots without suffering toxicity; the lower the concentration at which toxicity begins, the poorer the chloride tolerance. Among common crops, those with strong chloride tolerance include sugar beet, spinach, foxtail millet, kenaf, radish, chrysanthemum, rice, sorghum...

  • A Detailed Guide to Potassium Fertilizer Application Methods for Underground Tuber Crops

    How should potassium fertilizer be applied to underground tuber crops? Why should it be applied this way? Underground tuber crops such as potato, peanut, taro, sweet potato, yam, Jerusalem artichoke, carrot and others all have a potassium-loving nature and a relatively high demand for potassium, so in cultivation even more attention should be paid to applying potassium fertilizer to achieve high yields. For every 1000 kg of potato produced...

The factors that trigger the safety of agricultural products, especially quality and safety, include both natural and human aspects, among which pollution of the ecological environment, namely water, soil, air, organisms and other aspects...

  • What are the scientific application methods for bio-organic fertilizers?

    How should nitrogen fertilizer be applied to fruit trees? Please provide guidance. If there is too much nitrogen in the fruit tree, it will cause an imbalance between carbohydrates and nitrogen in the tree or disrupt its relationship with other elements, resulting in excessive vegetative growth, spindly branches and leaves, poor flower bud differentiation, and serious flower and fruit drop; in summer and autumn, when the nitrogen content in fruit leaves exceeds 2....

  • Application Methods and Technical Key Points of Pre-emergence Herbicides for Soybean

    How are growth regulators used on banana? Please advise. The growth, development, flowering and fruiting of banana are affected by nutrients and endogenous hormones within the plant as well as external environmental conditions (climate, soil, management level). During growth and development, it is often constrained by one aspect or another, which affects the yield and quality of banana fruit. Plant...
