Abstract

The invention relates to a cultivation method for overcoming continuous cropping obstacles of taros. The method comprises the following steps of: removing residual roots and leaves of previous crops in a continuous cropping field, bringing the residual roots and leaves out of the field, spreading lime nitrogen with an amount of 60-75 kg / mu onto soil surface, carrying out ploughing and uniform raking, carrying out watering until the soil is wet thoroughly, then carrying out covering with a white film, carrying out tight sealing, applying 500-650 kg / mu of a decomposed organic-inorganic compoundfertilizer 20 days before sowing, carrying out uniform rotary tillage and mechanical ridging, spraying a herbicide, and carrying out covering with a degradable black mulching film; disinfecting seed taros, carrying out drying in the air, adding seaweed essence for seed dressing, carrying out sowing, and irrigating roots with an amino acid water flush fertilizer with an amount of 8-11 kg / mu among rows in the seedling stage of 5-6 leaves of taros; and topdressing 100-130 kg / mu of an organic-inorganic compound fertilizer and 2 kg / mu of a seaweed essence among the rows at the initial stage of expansion. Compared with a conventional cultivation method, the method provided by the invention can solve the problems of nutrient element imbalance and biased deficiency of the taro continuous croppingfield, greatly reduces taro diseases, increases the yields of the taro seeds and mother taros, and improves the economic benefits of the taros.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a cultivation method for overcoming the obstacle of repeated cropping of taro. Background technique [0002] Taro is a traditional specialty agricultural product in China, and it is mostly used as a grain and vegetable crop harvested in one year. Due to the rich nutrition and high medicinal value of taro, the demand has increased year by year in recent years, and the large-scale and facility cultivation area has increased year by year. Due to the good economic benefits of planting taro, farmers often plant taro continuously in one piece of land, causing serious continuous cropping obstacles, manifested in: taro yield and quality decline, serious pests and diseases, and low commodity rate. The obstacle of repeated cropping is becoming the main bottleneck restricting the sustainable development of taro. [0003] The research found that the deterioration of soil physic...
