硼肥和锌肥在作物上的的作用,近几年已被普遍认可,但硼肥产品很少,纯度高、可溶性强的更少,本试验硼、硫酸锌肥、磷酸二氢钾3个产品进行试验。通过本次试验,验证硼肥和锌肥、磷酸二氢钾不同应用时期和不同用量在水稻整个生育过程中的重要性。1材料与方法1.1基本情况试验设在黑龙江省牡丹江科技园区,草甸黑土,土壤基本理化性状:有机质4.0g/kg、pH5.8、速效钾
The role of boron and zinc fertilizers in crops has been generally recognized in recent years. However, there are few boron fertilizer products with high purity and less soluble. Three boron and zinc sulfate fertilizers and potassium dihydrogen phosphate Product test. Through this experiment, to verify the boron fertilizer and zinc fertilizer, potassium dihydrogen phosphate different application periods and different dosage in the whole process of rice growth. 1 Materials and methods 1.1 The basic situation The experiment is located in Mudanjiang Science and Technology Park in Heilongjiang Province, meadow black soil, soil physical and chemical properties: organic matter 4.0g / kg, pH5.8, available potassium
