Winter wheat drought-resisting transpiration-resisting yield increasing method

Abstract

The invention relates to a winter wheat drought-resisting transpiration-resisting yield increasing method which includes the following steps that A. winter wheat is sown in the mode that four identical small line widths are 15cm respectively, a large line width is 20cm, and the sowing density is 300 particle / m<2>; B. watering is conducted in the jointing stage of the winter wheat with the water quantity as 54m<3> / mu, watering is not required in other growth periods, the fertilizer application quantity is consistent with that of local farmers, namely base fertilizer diammonium hydrogen phosphate is applied according to the ratio of 70 kilo / mu, and the application amount of the urea is 30 kilo / mu; C. fulvic acid is sprayed to the surfaces of leaves of the winter wheat in the heading stage, the dilution ratio is that the ratio of 8% commodity fulvic acid and water is 1: 1000, and the field application amount is 6.7L / mu; D. abscisic acid is sprayed on the surfaces of the leaves of the winter wheat in the grouting preliminary stage, the dilution ratio is that the mass ratio of 90% commodity abscisic acid and water is 1: 30000, and the field application amount is 6.7L / mu. According to the method, the planting mode of four-thick-one-dense of the winter wheat is selected, and the shortcoming that thick planting irrigation of the wheat is large in water amount is overcome to some extent by means of combination of the irrigation mode and transpiration-resisting agent spraying and by means of the sowing mode.

Description

technical field [0001] The invention relates to a drought-resistant, transpiration-resistant and yield-increasing method for winter wheat, which belongs to the technical field of agricultural planting. Background technique [0002] Drought has become one of the main limiting factors for increasing food production as water scarcity becomes more and more serious. In agricultural production, water shortage will lead to lower yield and lower quality of winter wheat. For example, drought occurring before and after anthesis (20-30 days before flowering or 10 days after flowering) will reduce the number and weight of winter wheat grains per spike. The main reason for the yield reduction is that the common response of winter wheat under drought stress is to reduce transpiration water consumption by closing stomata, but stomatal closure also limits CO 2 Fixation and photosynthetic processes. Therefore, more and more researchers have begun to pay attention to the role of stomatal r...

[0003] In the field of anti-transpiration agents, most of the research focuses on the research and development of new varieties and the further exploration of the application range and dosage of existing varieties. Although this research mode is conducive to the faster transfer of new products to production and application, it rarely involves different anti-transpiration agents.
