Problems solved by technology

However, due to the fact that the origin of Gexianmi is in the mountains, traffic congestion and other reasons have restricted the protection and research of its wild resources, and there has been a lack of scientific and reasonable resource multiplication methods, resulting in an increasingly scarce amount of wild resources.

Embodiment 1

[0017] The multiplication method of Gexianmi wild resources is aimed at the recovery and growth of wild resources in the origin of Gexianmi. Its implementation site is in Zouma Town, Hefeng County, Hubei Province. The specific operation steps are as follows:

[0018] A. Paddy field management during the rice growing season: Spraying herbicides is prohibited. About 3-4 months before rice planting, use deep plowing of 30-50cm, then irrigate (it is advisable to fill the whole field with water) and use long-term soaking (60 days) The above) method allows the weeds to rot under the soil and become an organic fertilizer source, and on the basis of the traditional method, rake the field once every 15-20 days, increase the number of harrowing times 2-3 times, to ensure that all weeds rot, no The source of weeds is retained; after the rice is planted, the weeds are manually removed. Use chemical fertilizers prudently, use as little or no chemical fertilizers as possible, especially nit...

Abstract

The proliferation process of wild common nostoc resource includes the following steps: 1. rice field management in rice growing season including using no herbicide and applying pesticide and farm manure properly; 2. ditching field after autumn harvest; 3. irrigating the field in autumn and winter to keep water depth not smaller than 10cm; 4. inoculating wild common nostoc seed after the temperature is higher than 15 deg.c in spring and irrigating properly to ensure the dry-wet alternation of 2 to 10; 5. field management to avoid external interference and destruction; and 6. picking proper to collect large ones and leaving small ones. The present invention can proliferate wild common nostoc resource and protect wild common nostoc resource effectively.

Description

technical field [0001] The invention relates to the field of protection and multiplication of wild plant resources, and more particularly relates to a method for multiplication of wild resources of Gexianmi. Background technique [0002] Nostoc sphaeroides kützing (Nostoc sphaeroides kützing) is a wild freshwater algae with the scientific name "Pseudosphaeroides kützing". It is a famous native product of Hefeng, Hubei, and has a long export history. Gexianmi is not a grain. The reason why it is called "rice" is because its shape is like rice grains, the grains are round after collection and drying, and the size is larger than rice grains after cooking. It grows in paddy fields, shallow ponds, lakes, streams, or on damp soil. It is spherical and gelatinous, and looks like fungus, so it is called "water fungus" or "field fungus"; it has no roots, stems, leaves, and floats It is in water, so it is also called "heavenly rice" or "heavenly dish". In fact, Gexianmi is a kind of ...
