Embodiment 1

[0034] In 2010, 57 taro seeds of Demo No. 1, four-year-old and above, were sown in the experimental field of Dehong Prefecture Agricultural Science Institute (910m above sea level). A total of 54 plants emerged, 48 plants bloomed and fruited, and 5.14kg of berries were harvested, about 20,000 grains. (See Table 1). On February 20, 2011, the seedlings were raised in plug trays. Before sowing, the seeds were soaked in water for 12 hours, the peels were peeled off, and the seeds were selected. The seedling substrate was prepared according to the technical step (3). After investigation, the emergence rate reached 91%, and the seedlings were transplanted. Demonstration planting 2.5 mu (see Table 2). The planting field is sandy loam, every 667m 2 Apply 3000kg of decomposed farmyard manure and 40kg of compound fertilizer (the ratio of N, P, and K is 15:15:15) as the base fertilizer, use 50kg of quicklime for soil disinfection, and use 2kg of ditrane to control field pests. Ridging ...

Embodiment 2

[0042] In 2010, He Kun in Hula Village, Zhafang Town, Mangshi City (830m above sea level) planted 45 taro seeds above the age of four. A total of 44 plants emerged, 35 plants blossomed and set fruit, and harvested 3.08kg of berries, about 13,000 pieces (see Table 4). In 2011, 2.6 mu were planted in the 6-year-old rubber forest by transplanting seedlings (see Table 5). The planting field is red loam soil, 1500-2000kg of decomposed farmyard manure and 40kg of compound fertilizer (N, P, K ratio of 15:15:15) are used as base fertilizer per mu, and 50kg of quicklime is used for soil disinfection. field pests. Ridging cultivation, transplanting in 3 batches, the number of effective seedlings per mu is about 3000. Since the 6-year-old rubber tree can provide natural shading conditions for konjac, there is no need to build a sunshade net. It is best to transplant in the evening. Spray 0.5% potassium dihydrogen phosphate for 8 weeks to enhance the stress resistance of the seedlings. ...

Embodiment 3

[0050] In 2010, in Mengli Village (860m above sea level), Mengmao Town, Ruili City, planted 50 taro species of Demo No. 1 over four years old in the semi-shade mountain. A total of 47 plants emerged, 36 plants bloomed and borne fruit, and 3.9kg of berries were harvested, about 15,000 grains (See Table 7). On February 17, 2011, 1.7 mu of seedlings were planted using the seedling transplanting method (see Table 8). The seedling raising substrate was prepared according to the ratio of 5 parts of leaf humus, 3 parts of decomposed farmyard manure, and 2 parts of raw red soil. The planting field is sandy loam soil, 2000kg of decomposed farmyard manure and 40kg of compound fertilizer (N, P, K ratio of 15:15:15) are applied per mu as base fertilizer, 50kg of quicklime is used for soil disinfection, and 2kg of diterene is used to control the field pests. Ridging cultivation, the effective seedlings per mu are about 7,000 seedlings, and a sunshade net with a shading rate of 85% is buil...

Abstract

The invention discloses a rapid propagation method of seed konjac De Mo No.1. The rapid propagation method of seed konjac De Mo No.1 includes the steps of seedling seed cultivation, seed collection and storage, seedling substrate preparation, plug seedling production, field transplanting, and harvesting and storage. Seed konjac is rapidly propagated by seedling seeds of De Mo No.1, propagation multiple of the seed konjac is up to 600 times which is 150 times of the propagation multiple in conventional rhizome cutting propagation, the bottleneck of low propagation coefficient of the seed konjac is broken through, and supply of fine breeds is increased effectively. The problem of high virus accumulation in conventional vegetative propagation can be solved, the seed konjac is rejuvenated naturally, and the quality of the seed konjac is increased. The problems of high cost and long seed konjac propagation period in propagation by tissue culture can be solved, planting benefit is increased, and planting risks are avoided. The technique of rapid propagation of fine Konjac breed is provided to solve the common problems of low propagation coefficient, high virus accumulation and fast seed nature degradation in seed konjac propagation. The rapid propagation method of seed konjac De Mo No.1 has the advantages of simplicity in operation, high seed konjac quality and low cost.

Description

technical field [0001] The invention belongs to the technical field of plant seed cultivation, and further belongs to the technical field of breeding of fine varieties, in particular to a method for rapidly propagating Demo No. 1 taro. Background technique [0002] Konjac ( Amorphophallus konjac ), also known as grinding taro or konjac, belongs to the family Araceae ( Areas ) Konjac ( Amorphophallus ). It has the effects of lowering blood fat, reducing the incidence of diabetes and colon cancer, and reducing weight. It is a kind of economic crop with high edible, medicinal, health care and industrial value. At present, there are problems in the production of konjac seed taro such as low reproduction coefficient, insufficient supply of improved varieties, serious virus accumulation in conventional vegetative propagation, high production cost in tissue culture propagation, and long reproductive life of seed taro. In order to improve planting efficiency, avoid planting ri...
