Characteristics and functions of common fertilizers
In sandy soil, all phosphate fertilizer should be used as base fertilizer, half of nitrogen fertilizer should be used as base fertilizer, and the other half should be topdressing by stages in the process of growth and development, and then the amount of water should not be too large to avoid fertilizer leakage after flood irrigation. In clayey soil, under the condition of water irrigation, phosphate fertilizer and nitrogen fertilizer of 2 to 3 can be used as base fertilizer, nitrogen fertilizer of 1 to 3 can be applied by stages, and none.

Common chemical control methods of storage pests
1. Parathion: parathion is a preferred grain protectant in the world, its chemical name is methyl pyrimidine (sulfur) phosphorus, and the commonly used dose for the control of stored grain pests is 5ppm. two。 Grain phosphorus: grain phosphorus is a grain protective agent developed by Chengdu Grain Storage Science Research Institute of the State Grain Bureau. it has a good control effect on stored grain pests, especially suitable for use in rural areas. The ratio of phosphorus consumption of preserved grain to that of raw grain was 1: 2500. That is, each bag of 100 grams of guaranteed grain phosphorus can be mixed with 250 kilograms of raw grain.

Pay attention to less phosphorus and more potassium in fertilizing wheat
First of all, the partial application of phosphorus to wheat is to increase the cost. Diammonium is quite expensive this year, with 64% of its retail price exceeding 3900 yuan per ton. Phosphorus is necessary, but there is no need for excess. Empirical data show that when 40-50 kg of ternary compound fertilizer containing 15% pure phosphorus is used as base fertilizer per mu, there is generally no shortage.

The proportion of nitrogen, phosphorus and potassium applied to potatoes should be appropriate.
The demand for nitrogen, phosphorus and potassium in potato is equally important. In the process of yield formation, nitrogen supply is the basis to ensure the formation of sufficient green leaf area for photosynthesis; phosphorus supply is also indispensable for tuber formation and starch accumulation; on the basis of sufficient nitrogen and phosphorus, potassium supply is necessary for carbohydrate assimilation in the early stage, aboveground to underground tuber transportation and starch accumulation in the later stage. The field test showed that the absorption ratio of nitrogen, phosphorus and potassium in potato was about 1 ∶ 0.5 ∶ 2.5.

Application of phytase in diets of pigs and chickens
Phytic acid or phytate is common in plant feed, and most of the phosphorus exists in the form of phytate phosphorus. Phytic acid can form a stable complex with metal ions such as calcium ion, iron ion, zinc ion and copper ion, and can also combine with protein and starch, reducing the activities of endogenous amylase, protease and lipase. The digestibility of nutrients decreased significantly. Phytic acid is not absorbed by monogastric animals, and most of it is excreted in the form of feces, which not only greatly reduces the utilization rate of phosphorus, but also causes environmental pollution, especially water pollution.
