Planting method of broad bean in rain-fed dry farming area

Abstract

The invention discloses a planting method of a broad bean in a rain-fed dry farming area, and belongs to the field of crop planting. The method includes steps of film covering and ridge forming, sowing, watering, fertilizing, topping and pinching, plant disease and insect pest management and timely harvesting, the specific process is as follows: a broad bean improved variety is selected, a land is selected, and a whole-film double-furrow sowing machine is used for film covering and ridge forming, sowing is performed according to sowing depth of 5-6cm and plant spacing of 18-23cm, and seeds are sown in the middle-lower part of the sunny ridge side of small and big ridges; the watering ensures soil is kept moistening in the early growth period of the broad bean, the soil ought to be dry in the medium-term growth of the broad bean, and waterlogging is prevented in the later growth period of the broad bean; potassium dihydrogen phosphate is used to spray for fertilizing in the flowering period of the broad bean; first-stage branches, second-stage branches, third-stage branches and invalid branches of high node order of the broad bean can be removed by the step of topping and pinching; and the broad bean is harvested after maturation. The broad beans are sown in the small and big ridges by whole-film double-furrow sowing, the small and big ridges all are covered with mulching films, invalid soil moisture evaporation can be reduced, after whole covering with the mulching films, land temperature can be improved in the early period, effective accumulated temperature can be increased, the growth period of the broad bean is prolonged, and maturation of the broad bean can be ensured.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a broad bean planting method. Background technique [0002] High-altitude arid mountainous areas are characterized by an altitude above 2000m and belong to rain-fed and dry-fed agricultural areas. The conventional planting method of broad bean is half-membrane flat planting, which has the problems of not being able to sow at the right time or difficult to emerge after sowing, incomplete seedlings, and poor seedling condition. Contents of the invention [0003] The purpose of the invention is to provide a method for planting broad beans in rain-fed and dry-fed agricultural areas. [0004] The technical scheme of the present invention is as follows: a method for planting broad beans in rain-fed and dry-farming agricultural areas, including the steps of ridge covering, sowing, watering, fertilization, topping and topping, management of diseases and insect pests, and timel...
