Technical requirements for formula fertilization
2020-07-01 12:22:15
Formula fertilization should meet the following 5 requirements.
First, the agreement between target yield and actual yield of formula fertilization reached over 90%, and other parameters were indexed.
Second, we must have a stable yield increase effect. The rate of increase in production in different years is: high-yield fields are stable at more than 5%, and middle- and low-yield fields are stable at more than 10%, and the quality of peanuts and the utilization rate of chemical fertilizers are correspondingly improved.
Third, it is necessary to rationally apply fertilization according to different soil qualities, soil fertility and different types of crops, and gradually improve the analytical testing methods and calculation methods, and quantify and semi-quantitativeize fertilization quantities.
Fourth, increase the input of organic fertilizer, and the input volume should be higher than the local average.
Fifth, it is necessary to facilitate the growth and development of crop rotation.
