Method for improving nitrogen fixation of legume plants

Abstract

The invention discloses a method for improving nitrogen fixation of legume plants. The method comprises the following steps of selecting legume plant seeds to be sown, taking the selected legume plant seeds as sowing materials, pretreating the sowing materials, washing the pretreated sowing materials with cold water, and independently storing the pretreated sowing materials; screening and selecting the pretreated sowing materials, and after damaged seeds and collapsed seeds in the sowing materials are selected out, enabling the sowing materials to be subjected to seed dressing treatment; and selecting proper rhizobium powder, proportioning the sowing materials and the rhizobium powder according to a ratio of 100: 1, and putting the elutriated sowing materials and rhizobium powder into a mixing device. According to the method, the seeds of the legume plants are treated, so that the epidermis of the seeds is adhered with the rhizobium powder, the nitrogen fixation effect of the seeds is greatly improved, and meanwhile, the planted seeds are subjected to topdressing treatment, so that the breeding effect of the legume plants is effectively improved.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for improving nitrogen fixation of bean plants. Background technique [0002] Soybean is one of the main grain and oil crops in my country. The annual planting area of ​​soybean in my country is about 140 million mu, accounting for 8%-10% of the grain planting area; among them, nitrogen is an important factor limiting the growth and production of soybean One, legumes have a high absorption of nitrogen, and the application of nitrogen fertilizers can directly and effectively increase soil inorganic nitrogen, thereby improving the nitrogen nutrition of legumes and increasing yield; taproots of legumes are well developed, with different Root nodule symbiosis, itself has nitrogen fixation; the nitrogen fixation effect of bean plants in the prior art is not good, and in the breeding stage, the nitrogen fixation effect of bean plants is low, thereby affects the growth qua...
