Abstract

The invention relates to a pinching method and anti-lodging cultivating method for fiber or oil and fiber flax. The pinching method includes the steps that after the flax gets into the full-bloom stage, when one to five capsules are expanded to be 4 mm to 6 mm, the flax is pinched only once, wherein the pinching length is 7 cm to 9 cm, pinching is mainly used for removing flowers and fruits, and remaining branches are kept. The anti-lodging cultivating method includes the steps of (1) planting the fiber or oil and fiber flax; (2) pinching the flax with the pinching method; (3) conducting harvesting. According to the pinching method and the anti-lodging cultivating method, the flax can be assisted in resisting lodging, the straw yield of the flax can be increased, and yield reducing of flax seeds and quality reduction of the seeds can also be avoided.

Description

technical field [0001] The invention relates to the field of flax planting, in particular to a method for topping and lodging resistance cultivation of flax for fiber or oil fiber. Background technique [0002] Flax (scientific name: Linum usitatissimum L.): It is an annual herb, which can be divided into three types: flax for fiber, flax for oil and flax for both oil and fiber. The stems of flax are erect, up to 1.2 meters high, the upper part is soft and waxy; the leaves are alternate, lanceolate, 20-40 mm long, 3 mm wide, with a glaucous surface; the petals of the flowers are 5, 15-25 in diameter mm, blue or white; the fruit is a capsule, the seed is flat and oval, and it likes cool and humid climate. [0003] Flax, especially flax for fiber and flax for oil fiber, because the flax stems are slender and easy to lodging, high temperature and rainy in the later stage of growth are prone to lodging in sheets. Once the flax plants are lodging, the quality of fiber yield and ...
