Organic fertilizer as a base fertilizer, can be spread on the seedbed, the local improvement of the soil; organic fertilizer can also be sprinkled on the surface, before sowing with the turn of the full application of fertilizer into the soil surface, and then tilled into the soil. Application principles are as follows: First, the facilities, points Shi, focus on the application, especially bio-organic fertilizer and functional organic fertilizer. From the fertilizer point of view, the focus on the role of fertilizer to play the most effective phosphorus fertilizer. If the direct application of phosphorus nutrients into the soil, the readily available phosphorus content of organic fertilizers is easily fixed by the soil, thus reducing fertilizer efficiency. Ditch Shi, point application of the key nutrients applied to the root system
