In ecological agriculture, bacterial fertilizer performed well in the cultivation of some vegetables and flowers. For example, Kumba Bio-fertilizer can enhance the plant's absorption capacity, including the absorption of mineral elements and water; increase the growth and development of plants, increase growth life, strengthen physiological metabolism; strengthen plant disease resistance and resistance; strengthen crop transplantation After the survival rate; improved the micro-ecological environment of plant growth. It is the special role of these fertilizers that makes these microbial products more and more supported by national policies and farmers. We will use Shandong agriculture as an example to discuss the development direction of China's agriculture.
Mr. Jia is the farmer of Shoufeng Family Farm in Shandong and he has planted 230 acres of vegetable greenhouses. In 2014, Mr. Jia participated in the "fertile soil project" piloted by the Shouguang City Government and solved the biggest problem that plagued farm production.
In Mr. Jia’s memory, farmer's fertilizer was used only in the past, and the annual grain output per mu was only two or three hundred pounds. Later, more and more fertilizers were used by farmers, and their grain output climbed year by year, up to two or three thousand pounds per mu. When the planting pattern of Shouguang greenhouse vegetables thrived, Mr. Jia and his wife invested in building vegetable greenhouses. The yield of greenhouses is even higher. For example, the output of cucumbers is as high as 20,000 kilograms per mu, which requires two to three times the chemical fertilizers in Daejeon. The anti-season vegetables also allow Jia Chongshan to earn dozens of times more income than farming.
However, with the increase in the amount of chemical fertilizers in recent years, Mr. Jia found that the experience of “manufacture more fertilizer and produce more†suddenly failed. The soil in the shed began to show signs of compaction, followed by an increase in pests and diseases. Vegetable output did not increase, but fell by 23%. The taste and quality of the melons and fruits grown were also worse than before. Mr. Jia found that greenhouse vegetables planted by other people in the surrounding areas generally exhibit similar phenomena. In 2011, Shouguang guided the farmers to scientific fertilization through new technologies (test soil formula) and new fertilizers (microbial fertilizers, water-soluble fertilizers) and other methods to gradually improve the quality of cultivated land. Since then, Mr. Jia only realized that the increase in diseases and insect pests led to the overuse of pesticides. The decline in the quality of cultivated land has led to a decline in the yield and quality of agricultural products. Essentially, they all stem from the abuse of crops, food and fertilizers.
Blind fertilization has led to a decline in the quality of arable land, which has become one of the most important issues in China's agriculture. In December 2014, Shandong Province's “Agricultural Quality Improvement Plan†(hereinafter referred to as “Planningâ€) issued by Shandong Province, the largest agricultural province, considered the overuse of chemical fertilizer as the primary cause of threatening the quality of cultivated land. The "planning" shows that Shandong Province's annual sales of purified fertilizer reached 4.727 million tons, accounting for 8% of the national chemical fertilizer application rate, and the nitrogen fertilizer utilization rate was about 30%, which is only 1/2 of the level of developed countries. The average amount of chemical fertilizer used for sowing acres is 27.2 kilograms, which is 6 kilograms higher than the national average, which is 19.2 kilograms higher than the world average.
As the amount of chemical fertilizers used in greenhouses is greater, the contradiction in the quality of cultivated land is even more pronounced. At present, there are 2.6 million mu of secondary salinization in the 13 million mu vegetable land in Shandong province. Soil acidification results in the imbalance of soil nutrients, the incidence of crops increases, and the quality of agricultural products declines. Plots with a pH of less than 4.5 generally result in a reduction in crop production by more than 30%. After four years of planting vegetable land, soil salinization has been increasing year by year, which has seriously affected crop yield and quality. (From: Economic Observer.)
