Application Of Biofertilizer In Greenhouse Vegetable Growth In Tinghu District Yancheng City

In recent years,the development of vegetable production in China has been relatively fast.It is already the largest country in the world in terms of vegetable cultivation area,but it is not a strong country in production.There is still a certain gap compared with developed countries.In the process of vegetable production,the technical content is low,there is no scientific basis as a guide,and the application of fertilizer and water does not form a quantitative standard.Farmers rely on many years of traditional production experience,blindly think that the higher the amount of fertilizer is,the higher the yield is,so that a large amount of fertilizer is applied..In addition,the topdressing is blind and random in time,and there is often a phenomenon in which the chase does not chase,and there is no need to chase after the chase.Since 2006,the Tinghu District of Yancheng City,Jiangsu Province has been developing facilities agriculture as a pillar industry for farmers to increase their incomes.Focusing on the construction of facilities and vegetables(including greenhouse vegetables),the company has expanded its market by scale and won the benefits by scale.The idea is to vigorously promote the development of facility agriculture in accordance with the working methods of "grasping demonstration,awarding compensation,technical guidance,and rural package".In 2014 alone,418 new greenhouses were built in the district,with a total output of 80 million kg of vegetables,an annual output value of 280 million yuan,a net income of 99.5 million yuan,and an increase of 10,000 yuan per household per person.Up to now,the facility vegetables in the whole district have grown from 1333 hm2 at the beginning of 2006 to 6667 hm2,and the total output of vegetables is 300 million kg,achieving an output value of 600 million yuan.The construction of vegetable communities in the whole district has achieved a new development and leapfrogging.Vegetable production has become a pillar industry for farmers to increase their income.The vegetable cultivation in Tinghu District is mainly based on cucumber,tomato and eggplant.Pepper,edible fungi and other vegetables are grown on a small scale.Due to the small-scale planting of farmers in the past,it is inevitable that the large-scale development of facility vegetables as a pillar industry will have problems in production management.The main reason is that farmers have insufficient mastery of scientific cultivation techniques,and they all use the old ones in the production process.Method,there is a problem and I don’t know how to solve it.In order to put forward reasonable suggestions for the fertilization of greenhouse vegetables in Tinghu District,through the investigation of the current status of organic fertilizer application in Tinghu District(including cucumber,tomato and eggplant),it can be seen that the fertilization method and fertilization amount of greenhouse vegetables with different planting years in Tinghu District exist.The difference is that the longer the planting period is,the less the application amount of inorganic fertilizer and organic fertilizer in the base fertilizer is,and the longer the limit is,the more significant the reduction is.The topdressing is just the opposite.The longer the planting period,the larger the amount of topdressing.From the input of N,P and K in the application of inorganic fertilizer alone,with the increase of planting years,the application amount of N and P increased significantly,and K did not change much.This is related to the fact that farmers have blindly thought that the more years they use greenhouse greenhouses,the lower their soil fertility will be.The more they need to increase the amount of fertilizer in the topdressing process to increase production.For a long time,China’s agricultural production has neglected the role of organic fertilizer,which in turn led to the continuous decline in the quality of cultivated land in China.At present,due to the lack of organic fertilizer and organic matter in China’s cultivated land,soil resistance and stability are declining,and the quality of agricultural products is declining.Excessive application of chemical fertilizers can also cause serious pollution to the soil,the atmosphere and the living environment.Therefore,it is the primary problem that needs to be solved urgently to find out the reasons for the low application rate of organic fertilizer in vegetable greenhouses in Tinghu District and accelerate the development of organic fertilizer industry.In this paper,the investigation on the application of organic manure in greenhouse vegetables in Tinghu District found that the problem of local organic fertilizer application is mainly due to the government’s subsidy policy to encourage farmers to apply organic fertilizer,the cost of organic fertilizer application is high,and the price of vegetables after organic fertilizer application is limited.Wait.In view of the above problems,this paper puts forward the following suggestions in the aspects of organic fertilizer application technology and policy support.Application technology:reasonable control of fertilizer input and application rate of organic fertilizer;scientific and rational application of nitrogen fertilizer,phosphate fertilizer and potassium fertilizer,and appropriate use of organic fertilizer instead of chemical fertilizer;scientific application of organic fertilizer;organic fertilizer and inorganic fertilizer combined application;Trace elements;strengthen the training of popular science knowledge,improve the technical level of farmers;carry out the investigation of the status of fertilization of greenhouse vegetables and formula fertilization.Policy support:Formulate relevant regulations to strengthen the utilization rate of organic fertilizer resources;provide policy support and financial support;strengthen technical training and guidance;promote the development of commercial organic fertilizer;and increase the construction of related infrastructure.
