specific Embodiment

[0042] In order to more specifically describe the detailed implementation process and method of the present invention, the heavy saline-alkali land area of ​​Huanghua City, Hebei Province was selected to carry out the double-season oil sunflower planting test to prove the feasibility of double-season oil sunflower plantation.

[0043] 1. Preparation before planting

[0044]According to the suitable planting area map of double-season oil sunflower, Huanghua City, Hebei Province was selected to carry out the planting experiment of double-season oil sunflower. At the same time according to the attached figure 2 , 3 In the two-season sowing date distribution map respectively, select the spring sowing period from April 10th to April 15th, and the summer sowing period from July 15th to July 25th; Beijing Tiankui Lide Seed Technology Co., Ltd. KWS204 (growth period 86-92 days) is a double-season spring sowing oil sunflower variety; select a mid-early maturing variety TK206 (growth...

Abstract

The invention relates to a double-season sunflower planting method which comprises that two-season sunflowers are planted in a double-season sunflower planting area of a Bohai Sea coastal saline area worked out through years of meteorological data and a geographic information systems method in spring and in summer; and the method comprises a first season sunflower spring planting and a second season sunflower summer planting. The whole process is divided into five parts, i.e. land preparation and fertilization, timely sowing, sowing method, field management and harvest. By fully satisfying the heat need required by the two-season sunflower crops, the invention reduces insect pest and the chemical use times, improves the land utilization rate, constructs the double-season sunflower planting method by accumulating temperature in the area suitable for growth, and realizes the high yield, the high quality and the high-efficiency plantating of the sunflower crops.

Description

technical field [0001] The invention relates to a method for planting double-season oil sunflowers, belonging to the technical field of agricultural planting and production. Background technique [0002] Oil sunflower is an important oil crop in my country. It has the characteristics of drought resistance, barren resistance, salt and alkali resistance, strong adaptability, and high oil content. As a nutritional and health-care oil product, oil sunflower oil contains high oleic acid and Linoleic acid, in which linoleic acid is an indispensable fatty acid for the human body. [0003] The hybrid oil sunflower among oil sunflower varieties has outstanding salt-alkaline resistance, and can still be planted and grown in areas with relatively high salinity. However, in my country's coastal saline-alkaline areas, local farmers are not very enthusiastic about planting oil sunflowers. The reason is that the flowering period of traditional spring-sowed single-season oil sunflowers coin...
