Embodiment 1

[0033] The method for releasing cress seed dormancy, the steps are as follows:

[0034] (1) Fully mix cress seeds and sand at a mass ratio of 1:2 to obtain a mixture of cress seeds and sand, and put the mixture into a plastic box for storage. After loading, there should be about 2 cm left on the surface of the plastic box Pure sand, in case of watering, the cress seeds float on the surface and are not well hidden by sand. Use bright yellow high-quality river sand for sand, which has better permeability than sediment and has almost no impurities that can float on the water surface. Use high-quality plastic boxes for storage containers. The plastic boxes are required to be easy to store, with a volume of about 40 liters and a height of about 32 cm, which is convenient for transportation, storage and moisture retention after sand storage. There should be 15 filter holes at the bottom of the plastic box. The size of the holes is about 5 mesh, which is convenient for water filtrati...

[0047] The method for releasing cress seed dormancy, the steps are as follows:

[0048](1) Fully mix cress seeds and sand at a mass ratio of 1:3 to obtain a mixture of cress seeds and sand, and put the mixture into a plastic box for storage. After loading, there should be about 2 cm left on the surface of the plastic box Pure sand, in case of watering, the cress seeds float on the surface and are not well hidden by sand.

Abstract

The invention discloses a method for breaking water fennel seed dormancy. The method comprises the steps as follows: firstly fully mixing water fennel seeds and sands in a mass ratio of 1: (1-3) to obtain a mixture of the water fennel seeds and the sands; then storing the mixture at the temperature of 5 DEG C to 35 DEG C for 25-40 days, and keeping the water fennel seeds in the mixture to be moist during the storage period; and separating the water fennel seeds from the mixture after the storage, and namely obtaining the dormancy-broken water fennel seeds. According to the method for breaking the water fennel seed dormancy, the problems that the dormancy exists in the water fennel seeds and untreated water fennel seeds are low in germination rate are effectively solved, so that the germination rate of the water fennel seeds is substantially increased, and the foundation for the wide domestic application of the water fennel seeds, export of the water fennel seeds and the soilless culture industrialization of the water fennels is established.

Description

technical field [0001] The invention relates to the technical field of cress cultivation, in particular to a method for releasing cress seeds from dormancy. 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. [0003] Cress 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. At present, domestic cress production does not use seed propagation, but adopts female stems for asexual reproduction. The important reason is t...
