Fertilizer is an important means of production to promote the growth and development of crops and improve the efficiency of agricultural production. In the face of a wide variety of fertilizers, combined with their own production needs, according to the type, characteristics, ingredients, and efficacy of fertilizers, can be said to be the necessary knowledge of many agricultural producers.
Farmers and families use fertilizer every day to help crops and gardens grow. Whether it’s a small garden for flowers or a large farm with thousands of acres of crops, fertilizers have been developed to help different crops grow in different soil and weather conditions.
Fertilizer is a substance added to the soil to improve plant growth and yield. Fertilizers were first used by ancient farmers, and with the discovery of the chemical needs for growing plants, fertilizer technology developed significantly. Modern synthetic fertilizers consist mainly of nitrogen, phosphorus, and potassium compounds, with the addition of secondary nutrients. The use of synthetic fertilizers has greatly improved the quality and quantity of food available today.
The fertilization method of potted plant fertilizer is different in each season. The spring and autumn season is the growing period of plants, and the demand for fertilizer is relatively large, so the amount of fertilizer needs to be increased. A small amount of fertilizer in summer, summer evening is the best time to fertilize, to avoid sunburn. When plants stop growing in winter, no fertilizer is needed.

Since the partially alcoholized PVA contains more acetate groups, and the volume of the acetate group is much larger than the hydroxyl group, there is a large steric hindrance, so that the partially alcoholized PVA cannot form a compact crystal structure. It can only form loose structures with large spaces between molecules, which can absorb more air.In the process of boiling size,because the size has a certain viscosity,it provents the small bubbles from escaping from the size surface,and forms the accumulation of small bubbles,which produces greater energy,thus making the size overflow the size mixing kettle.If there still is bubble in the sizing box,a foam layer will form form on the surface of the sizing,which will affect the operation of the worker and also affect the sizing quality.
The way to eliminatiing the foam is to add an antifoaming agent in the sizing box or the mixing kettle.The antifoaming agent is actually a sufactant with few hydrophilic groups,which can reduce the surface tension of the foam and rapidly break the foam,thereby reducing the accumulation of the foam and achieving the purpose of defoaming.
