Multifarious cultivation method for controlling continuous cropping obstacles of broad bean

Abstract

The invention discloses a multifarious cultivation method for controlling continuous cropping obstacles of broad bean, wherein the sowing time is from the first ten-day period to the middle ten-day period of October, but not later than October 15; wheat and broad bean are sowed at the same time; the wheat and the broad bean are interplanted in a ratio of six rows of wheat and two rows of broad bean; the planting ways and specifications of the wheat and the broad bean are as follows: sowing in line is adopted for the wheat at a sowing quantity of 150 kg.hm<-2> and a line spacing of 0.2 m; and spaced sowing is adopted for the broad bean at a row spacing of 0.3 m and a plant spacing of 0.15 m. The interplanting of the wheat and the broad bean is capable of improving the growth of the broad bean, increasing the quantity of rhizosphere microorganisms (bacteria, fungus and actinomycetes) and the metabolic function diversity of microorganisms, reducing the quantity of the rhizosphere pathogenic bacteria of the broad bean, reducing the content of organic acids and amino acids in the root exudate of the broad bean and reducing the occurrence damage of broad bean blight; and as a result, the occurrence ratio of the broad bean blight can be reduced by 9.2-45.5% and the condition of the broad bean blight can be reduced by 36.2%-48.6%.

Description

technical field [0001] The invention relates to a multi-ecological cultivation method for controlling obstacles to continuous cropping of broad beans, in particular to a method for controlling obstacles to continuous cropping of broad beans by intercropping wheat and broad beans. Background technique [0002] Broad bean is an important leguminous crop in the world. It has the characteristics of food, vegetables, feed and green manure, and has a high nitrogen fixation capacity due to its wide adaptability. It is planted in more than 70 countries around the world, with a planting area of ​​up to 260. million hectares. China's broad bean planting area and output rank first in the world. The broad bean planting area reaches 1.05 million hectares, accounting for 59% of the world's planting area, and its total output accounts for 61% of the world's total broad bean production. China's broad bean planting situation and production level affect and determine the world's broad bean p...
