Embodiment 1

[0025] The preparation of lily cultivation medium of the present invention, concrete steps are as follows:

[0026] Taking the preparation of a lily cultivation medium with a volume of 10L as an example, the single components of cornstalk, perlite, sand and peat were mixed in sequence according to the volume ratio of 3:2:1:4. At the same time, the usual cultivation substrate (7 peat: 3 perlite) was selected as the control (CK).

[0027] (1) Measure 3L corn stalks; (crushed and cut to a particle size of 2cm)

[0028] (2) Measure 2L of perlite (large particle size, rinse the dust with running water, and place it in a ventilated place to dry);

[0029] (3) Measure 1L of sand (medium particle size);

[0030] (4) Measure 4L peat;

[0031] (5) The above-mentioned individual components are fully mixed and set aside.

[0032] It needs to be pointed out that the total volume of each single component will decrease during the mixing process; in addition, the substrate must be watered...

Embodiment 2

[0042] The preparation of lily cultivation medium of the present invention, concrete steps are as follows:

[0043] Taking the preparation of a lily cultivation medium with a volume of 10.5L as an example, each single component of corn stalk, perlite, sand and peat is mixed in sequence according to the volume ratio of 3.5:2:1.5:3.5. At the same time, the usual cultivation substrate (7 peat: 3 perlite) was selected as the control (CK).

[0044] The particle size composition of the sand used is: 5mm accounts for 9%.

[0045] The particle size composition of the perlite used is: <1mm accounts for 7%; 1-3mm accounts for 64%; 3-5mm accounts for 29%.

[0046] The particle size composition of peat used is as follows: 5mm accounts for 24%.

[0047] (1) Measure 3.5L corn stalks; (crushed and cut to a particle size of 1.0cm);

[0048] (2) Measure 2L of perlite (wash the floating dust with running water and place it in a ventilated place to dry);

[0049] (3) Measure 1.5L sand;

[0...

Embodiment 3

[0055] The preparation of lily cultivation medium of the present invention, concrete steps are as follows:

[0056] Take the preparation of a lily cultivation medium with a volume of 9L as an example, each single component is corn stalk, perlite, sand and peat.

[0057] (1) Measure 2.5L corn stalks; (crushed and cut to a particle size of 2cm);

[0058] (2) Measure 1.5L perlite (large particle size, rinse the dust with running water, place it in a ventilated place to dry);

[0059] (3) Measure 1.5L sand (medium particle size);

[0060] (4) Measure 3.5L peat;

[0061] (5) The above-mentioned individual components are fully mixed and set aside.

[0062] It needs to be pointed out that the total volume of each single component will decrease during the mixing process; in addition, the substrate must be watered and settled before use, and watering can also reduce the temperature of the substrate. This requires consideration of a 30% volume increase when formulating the matrix. ...

Abstract

The invention provides a lily cultivating substrate made of corn stalks. The cultivating substrate is prepared in such a way that corn stalks, perlite, sand, turf, and the like are mixed according to a certain volume ratio. The cultivating substrate improves physicochemical properties of the prior single substrate, has wide sources of all single components, convenient material acquisition and lowcost, replaces a nonrenewable substrate, namely turf greatly used in the current flower production by a corn stalk part, reduces the production cost on the premise of ensuring the quality of lily cutflowers and has obvious benefits of society, economy and environmental ecology.

Description

technical field [0001] The invention relates to resource utilization of agricultural organic matter, in particular to the utilization of agricultural organic matter corn stalk in the field of cut flower production. Background technique [0002] Lilium spp., also known as Lily Garlic, Moro, Zhongfenghua, Zhongting, etc., is an autumn bulbous flower of the Liliaceae (Liliaceae) Lilium (Lilium). Ground cultivation can be used for annual production and flowers for four seasons. [0003] Lily is favored by people from all over the world for its elegant flower posture and rich colors, and has become a leader in the international flower market. It is also loved by the Chinese people for its beautiful meaning of "a hundred years of harmony", and it has developed rapidly in my country's flower industry in recent years. By 2007, the national cut flower planting area reached 33777.5 hectares, of which the planting area of ​​cut flower lily was 4716.7 hectares, and the annual sales vo...
