Method for determining companion planting of agricultural crops

Abstract

The invention discloses a method for determining companion planting of agricultural crops. The method includes: selecting suitable flowerpots and nylon bags according to the size and the quantity of cultivated crops, and placing two equal-sized nylon bags into the middle of one flowerpot; uniformly mixing soil with organic fertilizers according to the proportion of 10:1 so that a culture medium is prepared, and filling the sterilized culture medium into the nylon bags and the flowerpot; uniformly sowing three first crops in the nylon bags, sowing three second crops between a nylon membrane and the flowerpot and corresponding to the first crops in position, and marking positions by a permanent marker as the shortest distance between each first crop and the nylon membrane is as same as the shortest distance between each second crop and the nylon membrane; respectively sampling and determining rhizosphere soil of the first intercrops, the second intercrops, monoculture first crops and monoculture second crops and soil on the nylon membrane in the suitable growing periods of the first crops and the second crops; and analyzing soil microorganism crops according to soil sampling and determining results so as to determine whether the first crops and the second crops are suitable for companion planting or not. Therefore, the method is timesaving and laborsaving.

Description

Technical field [0001] The invention belongs to the technical field of agricultural crops matching planting, and in particular relates to a method for determining the matching planting of agricultural crops. Background technique [0002] With the continuous growth of the population, the food problem has become one of the major problems facing the world. Therefore, the use of the diversity of crops to increase food production has also become a focus and bright spot of current research. Many studies have reported that diversified planting can improve the field microclimate, reduce the occurrence and development of pests and diseases, and effectively increase the grain yield per unit area. In order to obtain a good planting pattern, it is not only necessary to analyze the genetic information and biological characteristics of the crops, but also to conduct field trials for two or more years to detect the quality of food crops and the yield per unit area. And there is no guarantee t...
