Embodiment 1

[0049] Embodiment 1 A kind of dense planting high-yield planting method of white asparagus

[0050] The cultivation method sequentially comprises the steps of raising seedlings, planting, garden clearing, film covering, simple harvesting of white asparagus and field management after harvesting the bamboo shoots.

[0051] Step 1. Seedling cultivation

[0052] Select "Shuofeng", "Grant", "Atlas" and other varieties suitable for planting white asparagus, and use plastic greenhouse nutrition pots to raise seedlings in early January, and select seedlings when the seedling age is 80d~90d Seedlings with a height of 30 to 35 cm and more than 3 aboveground stems and more than 7 underground storage roots are used for field planting.

[0053] Step two, colonization

[0054] One week before planting, dig a planting ditch according to the terrain trend. The width of the planting ditch is 1m, the depth is 0.5m, and the distance between the sidelines of two adjacent ditches is 1m. Raw soi...

Embodiment 2

[0083] Embodiment 2 planting density optimal experiment

[0084] Adopt the white asparagus planting method of embodiment 1, only change planting density, carry out test, experimental result is shown in Table 1;

[0085]

[0086] As can be seen from Table 1, the most preferred planting density of white asparagus is 2580 plants / mu; adopt the present invention, the output of white asparagus is 1800-2000kg / mu; the white asparagus of plantation: soluble sugar content is 3.5%~3.9%, soluble protein content 2.2~2.5g·kg -1 , crude fiber content is 1.2%~1.3%, vitamin C content is 375~400mg·kg -1 , the content of rutin is 800~850mg·kg -1 , the above percentages are mass percentages.

[0087] According to tests, the rate of first-grade bamboo shoots is 93% to 95% by adopting the invention to plant white asparagus, and the output is increased by 40% to 50%, and the economic benefit is increased by 60% to 80%.

[0088] Tests show that the invention greatly reduces the amount of labor...

Embodiment 3

[0091] Example 3 A special astigmatism heat insulation thermal radiation control film

[0092] The light astigmatism heat insulation thermal radiation control film adopted in step 4 of embodiment 1 comprises a light scattering layer and a light absorbing radiation layer;

[0093] Light scattering layer masterbatch formula:

[0094] The light-scattering layer masterbatch is rutile titanium dioxide and LDPE (low-density polyethylene) masterbatch; the specific mass ratio of the light-scattering layer masterbatch raw materials is as follows:

[0095] Recipe one:

[0096] The specific mass ratio of masterbatch raw materials is as follows:

[0097] 426 parts of rutile titanium dioxide

[0098] Stearic acid YA-Ⅱ-200 type 30 parts

[0099] PE wax 27 parts

[0100] LDPE420 copies

[0101] LLDPE97 parts

[0102] Recipe 2:

[0103] 426 parts of rutile titanium dioxide

[0104] Phthalocyanine blue 0.6 parts

[0105] Stearic acid YA-Ⅱ-200 type 30 parts

[0106] PE wax 26.4 parts...

Abstract

The invention provides a close-planting high-yield planting method for white asparagus and a special light diffusing and heat insulating heat radiation regulating and control film thereof. The planting method comprises the step of planting. The density is 2,380-2,660 per mu. The average line spacing of asparagus in an asparagus field is 1 m, and the planting plant distance of the asparagus ranges from 25 cm to 28 cm. In the planting process, the growing direction of an aerial stem, growing out firstly, of an asparagus seedling is consistent with the direction of a planting row, and the seedling is covered with soil of 5 cm to 6 cm after being planted. The width of planting furrows is 1 m, and the depth of the planting furrows is 0.5 m. The side boundary distance of two adjacent furrows is 1 m. The asparagus is planted through the method, planting density is 2,380-2,660 per mu, and the white asparagus grows vigorously. The yield of the white asparagus ranges from 1,800 kg/mu to 2,000 kg/mu, and is increased by 40% to 50% compared with a traditional method.

Description

technical field [0001] The invention relates to a simple and light-proof cultivation method of asparagus, in particular to a densely planted and high-yield cultivation method of white asparagus and a special light-scattering, heat-insulating and thermal-radiation regulating film, belonging to the field of agricultural technology. Background technique [0002] When the tender stems of asparagus germinate, they are harvested after softening with soil, and the white asparagus obtained is called white asparagus. White asparagus is mainly used for canning and processing, and can also be eaten fresh; at present, it is mostly exported to Japan, Europe and other countries and regions. [0003] The purpose of cultivating soil is to soften the tender stems, keep them out of the light, and let them grow in loose, moist soil. Generally, when the ground temperature of 10cm reaches 10℃, the tender stems have begun to germinate, and the cultivation of ridges begins 10~15 days after the bam...
