Embodiment 1

[0045] Golden Konjac ( Amorphophallus muelleri ) method for the same body relay growth of seedlings and multiple seedlings:

[0046] a. After the konjac fruit is fully mature, collect the plump seeds, then grade and air-dry according to the weight of the seeds. When the moisture content of the seeds is 20%-30%, store them under ventilation at a temperature of 10-15°C for later use;

[0047] b. Konjac seed treatment: soak the seeds with 3% potassium permanganate solution for 30 minutes to sterilize; then soak the seeds in cold water for 3 days, change the water once a day, and dry the surface moisture of the seeds after soaking; then use 500ppmGA3 + 50ppmIBA + 50ppm6-BA or Soak seeds with 0.1-3% thiourea for 12 hours;

[0048] c. Seedbed preparation: build a seedbed with a seedling substrate in the greenhouse, and keep the water content at 25-45%; the seedling substrate is a mixture of organic fertilizer: peat soil: soil=0.5: 1: 2;

[0049] d. Sowing and seedling management:...

Abstract

The invention relates to a multi-seedling autogenic relay growth method for seeds of amorphophallus muelleri, and belongs to the field of agricultural biotechnology. The multi-seedling autogenic relay growth method includes 1, processing the seeds; 2, soaking the seeds in solution containing 3% of potassium permanganate by 30 minutes to bactericide the seeds; 3, soaking the seeds in cold water for three days; 4, soaking the seeds in thiourea with the concentration of 0.1-3% or mixed liquid containing 400ppm GA3, 33ppm IBA and 33ppm 6-BA for 12 hours; and 5, breaking dormancy of the seeds and sowing the seeds. In the procedure for breaking the dormancy of the seeds and sowing the seeds for breeding seed bulbs, the moisture content of soil keeps 25-45% after the seeds are sown in the soil. As shown by test results, a germination rate of the seeds can reach 95% at least after seed dormancy breaking, an emergence rate of the seeds reaches 90% at least, the maximum weight of harvested seed bulbs of the amorphophallus muelleri is 710g, and the average weight of the harvested seed bulbs of the amorphophallus muelleri is 500g. The multi-seedling relay growth method has the advantages that a procedure is simple, and operation is convenient; by combining dormancy breaking with a germination accelerating and seedling raising mode, the germination speed and the germination rate of the seeds of the amorphophallus muelleri can be effectively increased, and the germination uniformity of the seeds of the amorphophallus muelleri can be effectively improved; and the quality of spouts is improved, the amorphophallus muelleri production period is shortened, and the method can be efficiently applied to large-scale production for commercial amorphophallus muelleri or seed bulbs in amorphophallus muelleri plantation.

Description

[0001] technical field [0002] The invention relates to a method for relay growth of konjac seedlings with multiple seedlings in one body, and belongs to the field of agricultural biotechnology. [0003] Background technique [0004] Konjac is a member of the genus Konjac (Araceae) Amorphophallus ) perennial herb, is the only one found so far that can synthesize glucomannan in large quantities ( konjac glucomannan, KGM ) plant populations, mainly distributed in tropical and subtropical regions of Asia and Africa, only a few Asian countries have cultivation, China and Japan are more common. Araceae Konjac plants, after 3-5 years of growth, some konjac bulbs will bloom. The process of flowering and seeding of konjac is sexual reproduction, and its cross breeding is self-pollination of the male and female stamens of the same plant under natural environmental conditions. Due to the premature maturity of the pistil, the same plant is sterile, and the probability of successf...
