Embodiment

[0026] A method for collecting cress seeds, comprising the steps of:

[0027] (1) Pull out the stems and leaves of the aboveground part of watercress: in the late stage of watercress breeding and production, at the end of September and early October, most of the mature watercress seeds fall off naturally. After the fanning field is dry (the soil is not compacted after being pressed, it is easy to cultivate), when the weather is fine, pull out the water celery stems and leaves in the fanning field, pull them up manually or with a ox, and let them dry in place for one to two days; Shake the cress stems and leaves, shake off the cress seeds that have not fallen off naturally, and finally remove the cress stems and leaves from the breeding field.

[0028] (2) Irrigate water to make cress seeds float up: Irrigate water to the breeding field where the stems and leaves have been pulled out, the water depth is 20cm to 30cm, and then stir the water in the field to stir the surface laye...

Abstract

The invention relates to the technical field of agricultural agronomy, in particular to a cress seed harvesting method. The cress seed harvesting method includes the steps of firstly, removing cress stems and leaves in a seed production field in late seed production phase of cress when most ripe cress seeds naturally fall, dropping the cress seeds not naturally falling in the cress stems and leaves into the seed production field, and removing the cress stems and leaves out of the seed production field; secondly, irrigating the seed production field to float the cress seeds to water surface; and thirdly, collecting the cress seeds in the seed production field with a screen. By the use of the cress seed harvesting method, harvesting cost is lowered, yield and quality of cress seed production are improved, and ripeness of the collected cress seeds is high.

Description

technical field [0001] The invention relates to the technical field of agricultural agronomy, in particular to a method for harvesting cress seeds. Background technique [0002] Cress is a perennial aquatic perennial herb of the Umbelliferae family. Cress is native to eastern Asia, and China is one of its origins. China has used the tender stems, leaves and petioles of cress for food since ancient times. It is mainly distributed in the Yangtze River Basin and the provinces and autonomous regions to the south, among which Jiangsu, Zhejiang, Hubei, Jiangxi, Anhui, Yunnan, Guizhou and Guangzhou have relatively large production areas. The national cultivation area is 25000hm 2 Left and right, there are shallow water cultivation, deep water cultivation and dry field modification cultivation in cultivation methods. In addition to China, cress is abundant in China, Japan, South Korea, North Korea, Indonesia and other East Asian and Southeast Asian countries also have relatively ...
