AI Technical Summary

Problems solved by technology

The main manifestations are as follows: First, the technological content of konjac production is not high. In konjac cultivation, the large ones are still sold and the small ones are kept. Farmers keep their own seeds, and a relatively large-scale planting base has not yet been established, resulting in serious degradation of the species, and a decline in quality and yield per unit area. ; The second is konjac soft rot, white silk disease is becoming more and more serious, and the annual loss is about 30%, especially the lower the altitude, the more serious the disease, and some even have no harvest
Seriously dampened the production enthusiasm of taro farmers

Embodiment 1

[0014] Embodiment 1: selection of propagation material: select the tissue-cultured taro species as the propagation material.

[0015] Sowing time: April 13

[0016] Sowing method: Select the Coptis chinensis land with fertile soil, moist soil and relatively flat land at an altitude of 1600-1700m, and apply 3000kg of decomposed farmyard manure and 70kg of ternary compound fertilizer per mu. The box planting and row spacing are as follows: 30cm×15cm for the weight of 20g-30g taro; 35cm×15cm for 31g-40g; 35cm×15cm for 41g-50g 20cm;

[0017] Treatment method and management: Propagation materials are treated with 1% solution of potassium permanganate for 15 minutes for sowing; planting seedlings are sprayed once with 1500 times solution of Keshade; mid-growth period is continuously sprayed twice with agricultural streptomycin 250ppm; Spray once with King Copper 1500 times solution, each time the dosage is 50kg-75kg per mu. The incidence rate of soft rot is zero, and the weight g...

Embodiment 2

[0018] Embodiment 2: Propagation material selection: Select conventional seed taro as propagation material.

[0019] Sowing time: April 10

[0020] Sowing method: Select Coptis chinensis at an altitude of 1,600 meters with fertile soil, moist soil, and relatively flat terrain. Combined with raking soil, apply 3,000 kg of decomposed farmyard manure and 70 kg of ternary compound fertilizer per mu. The single weight of 20g-30g is 30cm×15cm; the single weight of yam 31g-40g is 35cm×15cm; the single weight of yam 41g-50g is 35cm×20cm;

[0021] Material processing method and management: Propagation materials are treated with 1% potassium permanganate solution for 15 minutes, sprayed once with 1500 times solution of carbendazim at the seedling stage, once a week later with 1500 times solution of Kede, and used for agricultural use in the middle stage of production Spray once with streptomycin 250ppm, and spray once with King Copper in the later stage, each time the dosage is 50kg-75...

Embodiment 3

[0022] Embodiment 3: Propagation material selection: select taro penis for use as propagation material.

[0023] Sowing time: April 10

[0024] Sowing method: choose Coptis chinensis at an altitude of 1,600 meters, with fertile soil, moist soil, and relatively flat soil. Combined with raking soil, apply 3,000 kg of decomposed farmyard manure and 70 kg of ternary compound fertilizer per mu. The weight of a taro monomer with a weight of 20g-30g is 30cm×15cm; the weight of a single taro with a weight of 31g-40g is 35cm×15cm; the weight of a single taro with a weight of 41g-50g is 35cm×20cm;

[0025] Material treatment methods and management: Propagation materials are treated with 1000 times carbendazim for 15 minutes, sprayed once with 1500 times solution of Kede at the seedling stage, sprayed twice with agricultural streptomycin 250ppm in the middle stage, and sprayed once with King Copper in the later stage , each dosage is 50kg-75kg per mu. The incidence rate of soft rot is ...

Abstract

The invention relates to a konjac seed tuber cultivating method. The method konjac seed tuber cultivating method is characterized by comprising the following steps of: a. selecting cultivating materials; b. selecting sowing time; c. selecting a sowing method; d. sterilizing seed tubers; e. and managing the sterilization of a seedling stage and a growing period. Compared with the prior art, the konjac seed tuber cultivating method has the advantages that the seed tubers are good in characteristics, seeds are free from disease, and each acre of the seed tubers can be used for about six acres of soil.

Description

technical field [0001] The invention relates to a breeding method in the technical field of plant asexual reproduction, in particular to a method for cultivating konjac seed taro. Background technique [0002] Konjac (Amorphallus Konjac) is a perennial herbaceous plant of Araceae. There are more than 130 species in the world, mainly distributed in China and Southeast Asian countries. my country has a long history of cultivation. Konjac is rich in grape mannan and has more than 40 physical and chemical properties. It is an important raw material in food industry, pharmaceutical industry, chemical industry, oil drilling, construction industry, agriculture, etc. In recent years, due to the continuous expansion of market demand and the vigorous rise of the processing industry, the development of konjac industry has shown a good momentum of development. However, there are still many problems in terms of the current development status of my country's konjac industry. The main m...
