topdress उदाहरण वाक्य
उदाहरण वाक्य
- The total absorption of nitrogen increased with the amount of nitrogen topdressing , but the proportion of absorption nitrogen during the blooming period to total nitrogen were downtrend
- Topdressing fertilizers for swelling of kernels are manufactured at ambient temperature from organo - mineral fertilizers in the double - roll granulator without any drying , thereby giving full play to the characteristics of high nutrient content and quick fertilizer effect of mineral fertilizers as well as exploiting the advantages of soil amelioration and lasting fertilizer effect of the organic matter
- Kriged interpolation maps provided good indication of the spatial variability in crop yield and growth status . spatial interpolation and correlation analysis proved that spad lai was more indicative of crop growth status than individual variable , and useful for implementing growth season regulation and topdressing as needed
- According to the principle of nutrient balance and water requirement in cotton , the sub - model for fertilization and water management was developed by integrating the effects of soil characters , variety traits and yield target . the submodel can make decisions on the suitable total nutrient and water rates and distributions among main growth stages , ratio of organic to inorganic nitrogen , and the ratio of base to topdressing fertilizer
- Topdress different amount urea on cotton under film - mulching and drip irrigation during the blooming period , the result showed that content of nitrogen of root , leaf , leaf - stem and reproductive organ of cotton with nitrogen treatment were higher than non - treatment , but the increase had no relation with the amount of nitrogen topdressing
