In order to promote the development of Jiawang ecological agriculture, combined with the "263 provinces" special action plan requirements, agriculture four initiatives to open reduction of fertilizer efficiency activities.
First, organic fertilizer instead of chemical fertilizer. Mainly through the promotion of commodity organic fertilizer instead of fertilizer, driven by fertilizer applications. To improve the quality of cultivated land comprehensive demonstration project as the carrier, through government procurement, the purchase of organic fertilizer products nearly 1300 tons. At present, organic fertilizer has been served on the project area farmer or grower hands, for the upcoming summer autumn production. Commercial organic fertilizer nitrogen phosphorus and potassium content of not less than 5% tons of organic fertilizer, nitrogen phosphorus and potassium content of 50 kg, can be converted into 45% content of compound fertilizer 111 kg, with 1300 tons of commercial organic fertilizer can be decreased by 45% compound fertilizer 150 tons, realize the reduction of chemical fertilizer.
Two is to improve fertilization methods. Extend the fertilization equipment, mulching, fertilizer applicator, change into mechanical deep fertilization, fertilizing, enhance the comprehensive demonstration zone by the quality of cultivated land, in the village of purple Zhuang Zhen Dong and vigorously promote the integration of water and fertilizer project. After the government bidding, procurement and other procedures, the project started in late April. At present, the project has been laid underground pipeline, pumping station is under construction, spraying and drip irrigation facilities will also be installed in the near future debugging. According to the annual production and fertilizer requirement of the fruit and vegetable facilities, 100-150 kg of nutrient elements are needed per mu, and through the integration of water and fertilizer, under the normal fertilization management, the mu can be reduced by 45% kg and 150-200 kg of compound fertilizer.
Three is to formulate accurate fertilization standards. The application of fertilization results according to different soil conditions, crop yield and nutrient requirements of different target, establish suitable different regions, crop fertilization limits to be distributed, eliminate the random behavior of fertilization.
Four is to carry out regular, directional training. In the different growth stage of crops, especially in the slack period, district agricultural school will combine the training of farmers to invite relevant experts to the grower, professional cooperation organizations of pesticides, fertilizers and other inputs reduction efficiency of training.
