An efficient off-season cultivation method for promoting year-round production of lilies

Abstract

A highly efficient staggered-season cultivation method for promoting year-round production of lilies belongs to the technical field of lily planting. This staggered-season cultivation method uses wide-ridge and row planting. In October of the first year, the first batch of lily bulbs are planted at a high density on one side of each cultivation bed. When the lilies grow to a plant height of 55 to 65 cm, the second batch of lily bulbs are planted on the other half of the bed. When the first batch of cut flowers is harvested, the second batch of plants is in a vigorous growth period. At this time, a new round of planting begins in the ridge where the first batch of flowers is located, and this planting method is cyclical. Planting takes a total of 10 months throughout the year, and three batches of flowers are harvested. The yield per unit area can reach 174 to 210 plants / m 2 In July and August of the summer, naturally high temperatures are used to disinfect the greenhouse soil. This method changes the traditional planting form. It adopts a staggered cultivation method combined with high-density planting. While ensuring the year-round production of lily cut flowers, it significantly increases the annual output of lily cut flowers per unit area. It is simple and easy to implement, providing technical support for high-quality and efficient lily cultivation and sustainable development of the industry.

Description

Technical Field

[0001] The invention belongs to the technical field of lily planting, and in particular relates to a high-efficiency off-season cultivation method for promoting year-round production of lilies. Background Art

[0002] Lilies are perennial bulbous flowers of the genus Lilium in the Liliaceae family. They possess both ornamental and edible value and have a long history of cultivation in my country. The main production areas for ornamental lilies in my country are Yunnan, Liaoning, Guangdong, and Shanghai, with a cultivated area exceeding 120,000 mu (approximately 16,000 hectares). With the rapid development of my country's economy and the continuous expansion of the cut flower market, the production and consumption of cut lilies has gradually become a mainstream component of the floriculture industry, occupying a key position within the market.

[0003] Lilies prefer a cool, moist, semi-shaded environment. They are cold-tolerant and drought-tolerant, and some varieties are also relatively heat-tolerant. Winter temperatures in northern my country can drop as low as -20°C, while summer temperatures are relatively high, creating distinct seasons. Traditional greenhouse cultivation methods typically involve planting and harvesting twice a year. This results in high costs, low yields, and a concentrated market launch time, resulting in significant losses for both growers and flower companies. Currently, year-round availability of cut lilies is still a critical issue that needs to be addressed for the sustainable development of my country's lily industry. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a high-efficiency off-season cultivation method for promoting the year-round production of lilies.

[0005] The technical solution adopted by the invention is: an efficient off-season cultivation method for promoting the year-round production of lilies.

[0006] An efficient off-season cultivation method for promoting year-round production of lilies comprises the following technical steps:

[0007] (1) Select high-quality lily bulbs that are free of pests and diseases;

[0008] (2) Using high temperature and humid greenhouses in July and August to disinfect the soil;

[0009] (3) Effectively till the land, deep tilling 2 to 3 times, keeping the land clean and avoiding impurities and clods; after tilling the land, the soil needs to be exposed to the sun, organic fertilizer is used as base fertilizer and mixed with the soil, and after further deep tilling, the lines are set at fixed points at both ends to make ridges, with two furrows per ridge;

[0010] (4) Cover the bulbs with a quilt before planting to germinate at low temperature;

[0011] (5) Lily bulbs are densely planted on both sides of each furrow. After the first batch of lily bulbs are planted on one side of each bed (occupying 1 / 2 of the bed surface), the second batch of lily bulbs are planted on the other half of the bed surface after they grow to a height of 55-65 cm. When the first batch of cut flowers is harvested, the second batch of plants grow to a height of about 40 cm, and the third batch of lily bulbs are planted in the position where the first batch of flowers were originally located. This planting method is used for a total of 10 months throughout the year, and the remaining two months are used for greenhouse soil disinfection.

[0012] (6) Ventilate and dehumidify every day, provide shade under full sunlight, and remove the shade net after the lilies have spread their leaves.

[0013] The beneficial effects of the present invention are as follows: the method for promoting the year-round production of lilies changes the traditional planting form, adopts a staggered season cultivation method, and combines high-density planting to increase the yield of lily cut flowers per unit area while also achieving year-round production of lily cut flowers. The method is simple and easy to implement, and provides technical support for the sustainable development of the lily industry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following Figures 1 to 3 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: This example uses the highly efficient off-season cultivation method for promoting year-round lily production, described using the Siberian lily as an example, and includes the following steps:

[0020] Step 1: Select imported, pest-free 'Siberia' white lily bulbs with a circumference of 16 to 18 cm.

[0021] Step 2: Use the high temperature in July and August to disinfect the greenhouse soil.

[0022] Step 3: Effectively till the land, deep plowing 2-3 times to keep it clean and free of impurities and clods. After tilling, expose the soil to the sun. Mix organic fertilizer (cow manure) with the soil as a base fertilizer. Continue tilling the soil 25-30 cm deep and evenly. Then, mark out the lines at both ends to create ridges. Each ridge should have two furrows. The ridge surface should be level and straight, and the ridge width should be 1 meter during the tilling process.

[0023] Step 4: Before planting, cover the bulbs with a quilt and germinate them at a low temperature of 4°C. Leave them until the buds are about 5 to 6 cm long.

[0024] Step 5: Plant 'Siberia' bulbs densely on one side of the bed. In this embodiment, dense planting means that the distance between bulbs is kept at 11-12 cm, the row spacing is 50 cm, and the planting density is 58-70 bulbs / m 2 This example uses a large solar greenhouse (74 × 9 × 3.5 m) with 145 bulbs planted on each side. After the first crop of lily bulbs is planted on one side of each bed (occupying half the bed area), the second crop is planted on the other side of the bed after they grow to 55-65 cm. When the first crop of flowers is harvested and the second crop is approximately 40 cm tall, the third crop of lily bulbs is planted in the same location as the first crop. This planting method is repeated for a total of 10 months, with the remaining two months spent disinfecting the greenhouse soil.

[0025] Step 6: Ventilate and dehumidify every day, depending on the weather conditions, for example, 15 minutes, and provide 85% shade under full sunlight. Remove the shade net after the lilies have spread their leaves.

[0026] The lily yield produced by the efficient staggered-season cultivation method in this embodiment is compared with the traditional lily yield, as shown in Table 1. It can be seen that the yield per crop using the traditional cultivation method is about 13,000 plants, but the efficient staggered-season cultivation can achieve three crops of flowers a year, and the annual yield is nearly 1 to 2 times that of the traditional cultivation. It can be seen that the method of this embodiment is significantly superior to the traditional cultivation method. While increasing the annual yield of lily cut flowers per unit area, it also achieves year-round production of lily cut flowers.

[0027] Example 2: This example uses a highly efficient off-season cultivation method to promote year-round production of lilies, using 'Siberia' and 'Huang Tianba' lilies as examples, and includes the following steps:

[0028] Step 1: Select imported, pest-free 'Siberia' and 'Huang Tianba' lily bulbs with a circumference of 16 to 18 cm.

[0029] Step 2: Use the high temperature in summer to sterilize the greenhouse soil.

[0030] Step 3: Effectively till the land, deep plowing 2-3 times to keep it clean and free of impurities and clods. After tilling, expose the soil to the sun. Mix organic fertilizer (cow manure) with the soil as a base fertilizer. Continue tilling the soil 25-30 cm deep and evenly. Then, mark out the lines at both ends to create ridges. Each ridge should have two furrows. The ridge surface should be level and straight, and the ridge width should be 1 meter during the tilling process.

[0031] Step 4: Before planting, cover the bulbs with a quilt and germinate them at a low temperature of 4-5°C. Germination is completed when the buds are 5-6 cm long.

[0032] Step 5: Plant 'Siberia' and 'Huang Tianba' bulbs densely on both sides of each furrow. In this embodiment, dense planting means that the distance between bulbs is kept at 11-12 cm, the row spacing is 50 cm, and the planting density is 58-70 bulbs / m 2 In this example, 145 bulbs were planted in each furrow of the large solar greenhouse (74 × 9 × 3.5 m). After the first crop of 'Siberia' bulbs were densely planted on one side of the bed, the second crop of 'Huang Tianba' bulbs were planted on the other side when they grew to 55-65 cm. When the first crop of flowers was harvested and marketed, the second crop of 'Huang Tianba' flowers were approximately 40 cm tall. A third crop of 'Siberia' lily bulbs was planted in the same location as the first crop. When the second crop of 'Huang Tianba' flowers was harvested and marketed, the third crop of 'Siberia' lily bulbs was approximately 40 cm tall. This planting method allowed for a total of three crops of flowers to be planted throughout the year, spanning 10 months. The remaining two months were used for greenhouse soil disinfection.

[0033] Step 6: Ventilate and dehumidify every day, depending on weather conditions, for example, 16 minutes, provide 85% shade under full sunlight, and remove the shade net after the lilies have spread their leaves.

[0034] The lily yield produced by the efficient staggered season cultivation method in this embodiment is compared with the traditional lily yield. The staggered season cultivation method makes the annual yield of 'Siberia' and 'Huang Tianba' lilies about 1 to 2 times that of traditional cultivation. It can be seen that the method of this embodiment is significantly superior to the traditional cultivation method. It not only increases the annual yield of lily cut flowers per unit area, but also realizes the year-round production of lily cut flowers.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
