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 incr

Embodiment 1

[0017] In 2010 and 2011, fertilization research was carried out in the Weichang County carrot production base in the Bashang area of ​​Chengde, Hebei Province, which has a high degree of large-scale vegetables in the north. One week before carrot planting, apply basal fertilizer (20 cm deep) per acre. The base fertilizer is uniformly mixed with "Saizhong 28" and chemical fertilizer according to the mass ratio of 60%:40%. Of which fertilizer N-P 2 o 5 -K 2 O is 18%-5%-22%. The dosage per mu is 70 kg.

[0018] When turning the soil and applying solid base fertilizer, spray evenly on the soil surface with plant amino acid foliar fertilizer, with an amount of 30 kg per mu, to improve soil quality and increase the ability to resist heavy cropping.

[0019] The topdressing is divided into four applications during the plant growth period. At the seedling stage (seedling height 15 cm), 30 kilograms of plant amino acid foliar fertilizers are sprayed per mu, and 30 kilograms of ure...

Embodiment 2

[0024] In 2010 and 2011, fertilization research was carried out at the potato production base in Weichang County, Bashang District, Chengde, Hebei Province, which has a high degree of large-scale vegetables in the north. One week before potato planting, apply basal fertilizer (20 cm deep) per acre of furrow. The base fertilizer is prepared by mixing "Shen Liu 54", chemical fertilizers and organic fertilizers according to the mass ratio of 2%:1%:97%. Organic matter content in organic fertilizer > 30%, NPK nutrient content > 3%. Fertilizer N-P 2 o 5 -K 2 O is 15%-15%-15%. The dosage per mu is 3500 kg.

[0025] When turning the soil and applying solid base fertilizer, spray fulvic acid foliar fertilizer evenly on the soil surface at an amount of 30 kg per mu to improve soil quality and increase the ability to resist heavy cropping.

[0026] The topdressing fertilizer is applied four times during the plant growth period. At the seedling stage (seedling height 15 cm), 25 kg o...

Embodiment 3

[0031] In 2010 and 2011, fertilization research was carried out in the Weichang County carrot production base in the Bashang area of ​​Chengde, Hebei Province, which has a high degree of large-scale vegetables in the north. One week before carrot planting, apply basal fertilizer (20 cm deep) per acre. The base fertilizer can be made by uniformly mixing chitin with active function and chemical fertilizer according to the mass ratio of 70%:30%. Of which fertilizer N-P 2 o 5 -K 2 O is 18%-5%-22%. The dosage per mu is 60 kg.

[0032] When turning the soil and applying solid base fertilizer, spray seaweed foliar fertilizer evenly on the soil surface at an amount of 30 kg per mu to improve soil quality and increase the ability to resist heavy cropping.

[0033] The topdressing was applied in four times during the plant growth period. At the seedling stage (seedling height 15 cm), 25 kg of seaweed foliage fertilizer was sprayed per mu, and 30 kg of urea was topdressed per mu in ad...

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...
