Abstract This experiment was conducted to study the effects of applying Ames P and K on the growth and yield of field crops wheat and sweet potatoes. The results showed that the use of Ames bio-phosphorus potash fertilizer can promote the growth and development of wheat, significant increase in yield, reducing the amount of fertilizer, less pollution, high ratio of production and investment, with great promotion value.

Key words Ames bio-phosphorus potassium fertilizer sweet potato growth yield

“Ames” Bio-P Potassium Fertilizer is a kind of compound microbial agent compounded by three kinds of bacteria. It was developed and produced by Beijing Century Ames Biotechnology Co., Ltd. It is now widely used throughout the country to further verify its use. As a result, we chose Dengzhou City, Henan Province, which has a large area of ​​promotion, to conduct two-year verification tests on the representative crops of wheat and sweet potatoes. This is the result of a two-year verification experiment.

First, the contents and methods of the experiment

1. The main content of the experiment: under the condition of certain quantified fertilizer as base fertilizer, the experiment of applying and not applying bio-phosphorus and potassium fertilizer on wheat and sweet potato will further verify the effect of applying bio-phosphorus and potassium fertilizer on the yield of wheat and sweet potato.

2. experiment material

Wheat varieties: Yumai 18--64 lines, which are commonly grown in the area.

Sweet potato varieties: They are commonly grown in the area.

The choice of test sites: Daigang Village of Gaoji Township, Yaoxiang Village of Chengjiao Township, and Zhoulou Village of Qidong Township in Dengzhou City, a total of three pilot sites representing Dengzhou Yellow Earth, Huanglao Earth and Shajiang Black Soil. The three soil types together accounted for more than 85% of the cultivated area of ​​the city, and the experimental ground force was moderately high.

3. experiment method

All three trial sites were randomized.

Wheat: In 1998, based on the application of ammonium bicarbonate, 2 kg of bio-phosphorus and potassium fertilizer were added on the basis of ammonium bicarbonate. In 1999, 2 kg of bio-phosphorus and potassium fertilizer were applied on the basis of 25 kg of ammonium bicarbonate. In the two years, the single application of ammonium bicarbonate without biofertilizer was used as a control, and local production habits were used to manage. The aboveground height and tillering status were investigated in the three-leaf stage, the tillering stage, the wintering stage and the returning jointing stage, respectively. Rooting conditions, heading and flowering, and filling stage were examined for the resistance and lodging resistance of wheat, and three factors were involved in mature production.

Sweet potatoes: Taking summer potato as the object, 98, 99 respectively chase 2 kg of bio-phosphorus and potassium fertilizer in the harvest period of sweet potato, apply 25 kg of ammonium bicarbonate during the ridging period, and use bio-phosphorus fertilizer as no control, according to local production habits. Focus on the number of potato blocks and the yield per plant that have a significant effect on the yield.

Second, test results and analysis

From this table, it can be seen that there is no significant difference between the three-leaf stage and the tillering stage, and there is a significant difference between the wintering and jointing stages, the plant height, single tiller, mu groups, and secondary roots. A good comprehensive effect of Musk's biological P and K fertilizer on the growth and development of wheat.

This statistical table further shows that the use of bio-phosphorus fertilizer to increase production performance in the comprehensive effect of three factors into the production, but also further proved the biological phosphorus and potassium fertilizer to promote the growth and development of wheat a good effect.
