Embodiment Construction

[0020] A method for inducing seedlings of Elephant Grass in soilless culture, comprising the following steps: (1) selecting the source of Elephant Grass mother plant, which can come from field, potted plant, hydroponics or other matrix cultivation, according to the seedling purpose Determine the corresponding source according to different requirements such as quantity, quality, etc. The stem nodes and root necks of Elephant Grass are the important parts where axillary buds or adventitious buds occur. For mother plants such as hydroponics, it is advisable to choose robust elephant grass plants with a height of 50cm-70cm, such as figure 1 shown; (2) treatment with cytokinin plant growth regulators to induce the emergence of Elephant Grass, after determining the mother plant of Elephant Grass and its required number, in the middle and late May of that year, the temperature reached 15°C, and Elephant Grass had already reached 15°C. When starting to turn green (for example, in arti...

Abstract

The invention discloses a method for inducing elephant grass to become a seedling fast in soilless culture. The strong tiller sprouting and adventitious root growing capacity of the elephant grass is utilized, spraying processing is carried out on the cultivated elephant grass with 0.2-5.0mg/L plant growth regulator 6-benzyladenine of a cytokinin type, and processing time is 1-2 weeks. When a great number of adventitious buds of the elephant grass are generated and grow to be 6-10cm or have 2-3 leaves, the adventitious bud is cut down from a stock plant with a trenchant edge and is placed in culture solutions with water, 0.20mmol/l K2SO4, 0.15mmol/l MgSO4, 0.06mmol/l KH2PO4, 0.5mmol/l Ca(NO3)2, 0.25mmol/l KCI, 12.5 micronol/l Fe(II)-EDTA, 2.5 micronol/l H3BO3, 0.25micronol/l MnSO4, 0.15 micronol/l ZnSO4*5H2O and 0.02 micronol/l(NH4)6Mo7O24*4H2O to be induced to take root. After the root of the adventitious bud is 2cm, the adventitious bud is placed in culture solutions with reduplicated nutrient elements to continue to be cultivated for a week to become the seedling, and the problem of how to fast obtain the seedling of the elephant grass without tissue culture and with low cost is solved.

Description

Technical field [0001] The invention relates to a plant cultivation method, in particular to a method for inducing rapid seedling growth of elephant grass in soilless cultivation. Background technique [0002] Elephant grass is a kind of perennial clumped large gramineous fine forage widely cultivated in tropical and subtropical regions. It is widely used and has high economic value. However, due to the low seed setting rate, low seed germination rate and slow growth of seedlings of elephant grass, asexual reproduction methods such as ramification method and cutting method are often used in current production. These propagation methods often take a long time and have a low seedling rate. And the number of reproduction is limited; and the rapid propagation of elephant grass by cell engineering methods such as tissue culture often needs to go through links such as callus induction, cluster bud induction, cluster seedling proliferation, strong root culture, seedling hardening a...
