How should phosphate fertilizer be applied during wheat cultivation?
How should phosphate fertilizer be applied when growing wheat? Please advise: in wheat production, some places either emphasize nitrogen and neglect phosphorus, or apply phosphorus the wrong way, which reduces the yield increase. Scientific phosphorus application in wheat should pay attention to the following points: 1. Look at the soil organic matter content. In soil with organic matter content below 1.5%, the yield-increasing effect of phosphorus application is...

Grape Growing Techniques: How Should You Fertilize to Make Grapes Sweeter?
How should you fertilize to make grapes sweeter? Please explain the fertilization methods. To make grapes sweeter, you can refer to the following fertilization methods: 1. Focus on base fertilizer. Around October, that is, late autumn, is the best time to apply base fertilizer to grapes. When applying base fertilizer, pay attention to applying organic fertilizer together with microbial bacterial fertilizer, applying 4000 jin to 5000 jin of decomposed organic fertilizer per mu, and 2 to 3 kg of Jinbaobei microbial bacterial fertilizer; in addition, do not neglect the combination of chemical fertilizers (mainly nitrogen and phosphorus fertilizers), applying 15 to 20 kg of urea or 30 to 40 kg of ammonium sulfate per mu. The base fertilizer should be buried into the soil together with deep plowing. This fertilization method of organic fertilizer plus microbial bacterial fertilizer plus chemical fertilizer not only provides quick-acting nutrients to the grapes, but also improves the soil micro-ecological environment and plays a role in improving the soil. Reason: The beneficial microorganisms in Jinbaobei microbial bacterial fertilizer, through the secondary metabolites produced by their own life activities, activate the soil, increase the number of soil aggregates, enrich the soil, increase the absorption rate of grape roots, and make full preparations for the flowering and fruiting of grapes.

How should eggplants be managed during summer planting for the best results?
How should eggplants be managed well when planted in summer? Please explain. Summer eggplants, because their growing period falls in a season of high temperatures, frequent rain, and frequent pests, diseases, and weeds, have low and unstable yields. To achieve an ideal yield, the following field management measures should be carried out well: 1. Apply the "three" fertilizers properly: after the seedlings survive transplanting, apply a good seedling-promoting fertilizer, applying 1000 kg of 20% human excrement and urine per mu or applying 10-15 kg of compound fertilizer in holes; when the first eggplant fruit swells, apply a good first-fruit fertilizer, applying 1500 kg of human excrement and urine or applying 15 kg of compound fertilizer in holes; apply a good fruit-fattening fertilizer, applying 2000 kg of human excrement and urine or 20 kg of compound fertilizer when eggplants enter the fruiting stage.
