Fertilizing method for overcoming replant disease of tuber vegetables in northern cold areas

Abstract

The invention discloses a fertilizing method for overcoming replant disease of tuber vegetables in northern cold areas; and aiming at the condition that the intensive tuber vegetable production in northern cold areas encounters the replant disease which causes yield reduction, the invention provides a fertilizing method for overcoming the yield reduction caused by the replant disease of tuber vegetables in northern cold areas. Materials used by the fertilizing method contain a great quantity of secondary and trace elements required by vegetable growth; after the fertilizing method is used, carrot has an increase of 545kg per mu, the incidence is decreased below 2% and the rate of growth is 17%; and potato has an increase of 445kg per mu and the rate of growth is 16%. According to the fertilizing method, the problems that rotation of crops cannot be carried out in scale vegetable planting so as to cause yield reduction and the incidence of soil-borne diseases is on the rise are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a fertilization method for controlling continuous cropping tuber vegetable disease occurrence and yield decline in northern cold and cool regions. Background technique [0002] With the development of social economy, the consumption of vegetables is increasing day by day, coupled with profit-driven reasons, the number of farmers engaged in vegetable production is also increasing. The industrialized production of vegetables has led to the emergence of a number of characteristic large-scale professional production areas in various parts of our country. The specialization of vegetable production has undoubtedly led to the intensification of continuous cropping obstacles, resulting in a decline in yield and quality. [0003] Due to the cold weather in autumn and winter in the cold northern regions, only one season can be planted each year. However, the planting area...

Problems solved by technology

However, the planting area of ​​potatoes and carrots is rapidly expanding, but the land area is limited, so it is difficult to fall stubble, which leads to the gradual increase of soil-borne diseases. Moreover, due to factors such as poor production management and unscientific fertilizer input, the disease resistance of crops is weakened, and pesticides and chemical fertilizers are used. It is getting bigger and bigger, and the frequency of medication is also increasing, falling into a vicious circle of disease incidence, medication, and fertilizer use.

However, the current conventional fertilizers are difficult to provide all the elements for plant growth at the same time. The accumulation of large amounts of elements and the lack of medium and trace elements will cause the imbalance of soil nutrients and the decline of soil nutrient conversion ability.

And then seriously affect the improvement of vegetable yield and quality
