Abstract
Description
Technical Field
[0001] The present invention belongs to the field of agricultural production, and particularly relates to a greenhouse production method for early and multiple harvests of ginger shoots. Background Art
[0002] Ginger shoots are a kind of perennial special vegetable, which are the tender stems of ginger, rich in various amino acids, proteins, vitamins and other nutrients, and have high edible value. At present, the market selling price of ginger shoots is 50 - 60 yuan / kg.
[0003] Ginger shoots are mainly on the market from March to April every year, and the supply cycle is short. In early spring, the temperature is low. At present, small arch sheds or greenhouse sheds are used to cultivate ginger shoots (a method for annual cultivation of ginger shoots in greenhouse sheds, Xiao Zhibin, etc.; a high-efficiency cultivation technology for softening ginger shoots in greenhouse sheds in Shiyan area, Ming Changchun, etc.). Generally, only 1 - 2 times of ginger shoots can be harvested, and it is necessary to combine the cultivation situation of ginger, whether the tubers are thick, whether there is a cold snap in early spring, and the length of the cold snap time, etc. all affect the harvest of ginger shoots. Summary of the Invention
[0004] The purpose of the present invention is to provide a greenhouse production method for early and multiple harvests of ginger shoots, so that ginger shoots can be produced from December to March of the following year, and ginger shoots can be on the market during the Spring Festival to meet the healthy food during the Spring Festival.
[0005] The purpose of the present invention is achieved by the following technical solutions: A greenhouse production method for early and multiple harvests of ginger shoots, comprising the following steps: (1) Seed selection In early November, select ginger tubers as seed tubers.
[0006] (2) Loading into a foam box Load humus soil into the foam box, smooth it, and load the seed tubers.
[0007] (3) Covering soil and watering After loading humus soil and seed tubers into the foam box, then cover with humus soil or raw soil, smooth it, water the soil, and cover the foam box.
[0008] (4) Cultivating and harvesting ginger shoots for the first time Stack multiple layers of foam boxes in the greenhouse, adjust the greenhouse temperature to 25 - 30 °C, continuously cultivate for 38 - 42 days, and then harvest ginger shoots. Among them, water once on the 20 - 22nd day of cultivation.
[0009] (5) Continuing to cultivate and harvesting ginger shoots from the second to the seventh time After harvesting the ginger shoots, water once, adjust the greenhouse temperature to 22 - 28°C, and continue cultivation. Harvest the ginger shoots every 13 - 15 days. Repeat this step for a total of seven times.
[0010] In step (1), the ginger rhizomes are preferably thick, with few fibrous roots, many buds, and free from diseases and pests.
[0011] In step (1), the seed stems are preferably stacked for 3 - 4 days to reduce the moisture on the surface of the seed stems.
[0012] In step (2), it is preferred to line the foam box with nylon film first and then fill it with humus soil, which is convenient for later removal of the soil and reuse of the foam box.
[0013] In step (2), the thickness of the humus soil is preferably 4 - 5 cm.
[0014] In step (2), the spacing between the seed stems is preferably 0.5 - 1 cm.
[0015] In step (3), the thickness of the humus soil or raw soil is preferably 3 - 4 cm.
[0016] In steps (4) and (5), the harvested ginger shoots are preferably those with a height of 15 - 20 cm.
[0017] The greenhouse production method for early and multiple harvests of ginger shoots further includes the step of returning the rhizomes to the field for cultivation: after harvesting the ginger shoots seven times, place the rhizomes in the foam box in the field for cultivation. After the second year, select suitable rhizomes as seed stems and use the above steps to cultivate ginger shoots in the greenhouse.
[0018] The present invention has the following advantages and beneficial effects: The method of the present invention is simple, easy to operate, and convenient for popularization. The method of the present invention can enable the ginger shoots to be marketed multiple times and in batches between December and March of the following year, greatly improving the production efficiency and economic benefits.

[0021] The present invention will be further described in detail below with reference to the embodiments, but the embodiments of the present invention are not limited thereto. Embodiment
[0022] A greenhouse production method for early and multiple harvests of ginger shoots includes the following steps: (1) Seed selection In the first ten days of November, select thick yanghe tubers with few fibrous roots, many buds, and no diseases or pests as seed tubers. Stack the seed tubers indoors for 3 - 4 days to reduce the moisture on the surface of the seed tubers.
[0023] (2)Load into a foam box Select a foam box with length, width, and height of 500mm, 380mm, and 270mm. Load 4 - 5 cm of fermented and decomposed humus soil into the foam box, smooth it, load the seed tubers, and keep a spacing of 0.5 - 1 cm between the seed tubers.
[0024] (3)Cover with soil and water After loading the humus soil and seed tubers into the foam box, cover with another 3 - 4 cm of fermented and decomposed humus soil or raw soil without impurities, smooth it, clean the soil around the foam box, water the soil in the foam box until it is thoroughly watered and there is no waterlogging, then cover the foam box.
[0025] (4)Cultivate and harvest yanghe shoots for the first time Stack 5 - 7 layers of foam boxes in the greenhouse, adjust the greenhouse temperature to 25 - 30 °C, and continue to cultivate for 40 days. Then harvest the yanghe shoots that have grown to 15 - 20 cm in height. This is the first harvest. Among them, water moderately once on the 20th - 22nd day of cultivation.
[0026] (5)Continue to cultivate and harvest yanghe shoots from the second to the seventh time After harvesting the yanghe shoots, water moderately once, adjust the greenhouse temperature to 22 - 28 °C, and continue to cultivate. Harvest the yanghe shoots that have grown to 15 - 20 cm in height every 15 days. Repeat this step, and a total of seven times of yanghe shoots can be harvested.
[0027] (6)Return the tubers to the field for cultivation Plant the tubers in the foam box in the field. After the second year, dig out the tubers, select thick tubers with few fibrous roots, many buds, and no diseases or pests as seed tubers, and use the above steps to cultivate yanghe shoots in the greenhouse.
[0028] The method of the present invention can enable yanghe shoots to be listed in multiple batches from December to March of the following year. Each foam box can produce about 1.4 kg of yanghe shoots. Calculated at 50 - 60 yuan / kg, each foam box can generate an economic benefit of 70 - 84 yuan.
[0029] The above embodiments are only used to help illustrate the present invention. The implementation manners of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
