Method for planting green and pollution-free okra

Abstract

The invention relates to a method for planting green and pollution-free okra, belongs to the technical field of agricultural planting and particularly relates to a method for planting okra and provides a method, which is capable of quickening the growth speed of the okra, increasing the yield and having no pesticide remains, for planting the green and pollution-free okra. The method for planting the green and pollution-free okra comprises the following steps of (1) carrying out sowing and seedling raising through a seedling transplantation method, wherein sowing and seedling raising in a northern area are usually carried out in a cold frame and a sunlight greenhouse in early march and middle march; (2) carrying out field management, cultivating, weeding and ridging, wherein the air temperature is lower after seedling emergence or fixed planting, so that the cultivation can be continuously carried out for twice, in order to increase the ground temperature and promote the seedling recovering; (3) thinning, wherein first thinning can be carried out during core splitting, and residual weak seedlings can be thinned out; second thinning can be carried out while 2 to 3 pieces of true leaves appear, and strong seedlings can be selected; final singling can be carried out while 3 to 4 pieces of true leaves appear, and one plant remains in each hole; (4) watering, wherein higher air and soil moisture contents are required during a growth period of the okra, artificial sprinkling irrigation needs to be carried out in the morning and in the evening while water is shorted within 20 days after planting, and mechanical sprinkling irrigation or furrow irrigation can be carried out after seedlings grow a little larger.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a method for planting okra. Background technique [0002] Okra refers to annual, biennial or perennial herbaceous plants. There are about fifteen species. The flowers are large and beautiful, and can be used in gardens, and some species can be used as medicine or food. This genus is very similar to Hibiscus, the main difference is that the former has a spathe-shaped calyx, one side is cracked, and falls off in a ring when fruiting, while the latter calyx is persistent and easy to distinguish. Among them, okra, also known as okra, coffee ambrette, and eggplant, is native to Africa, and there are wild species in my country. It is currently widely cultivated in tropical regions such as Europe, Africa, the Middle East, India and Southeast Asia. Okra has become a high-end nutritious and healthy vegetable that people are chasing after, and it is popular all over the w...

Problems solved by technology

However, the existing okra planting technology is not perfect. The growth rate of okra is slow, the yield is not high, and there are pesticide residues, so it cannot be green and pollution-free.
