Description

Cultivation method of gynura bicolor

Technical Field

The invention relates to a plant cultivation method, in particular to a gynura bicolor cultivation method.

Background

The gynura bicolor is a perennial evergreen perennial root herbaceous plant, and the tender stem leaves of the gynura bicolor have higher edible and medicinal values. Every 100 g of gynura bicolor tender stem and leaf contains 92.79 g of water, 0.18 g of crude fat, 2.11 g of crude protein, 0.94 g of crude fiber, vitamin A5644 international unit, vitamin B1, 0.01 mg, vitamin B2, 0.13 mg, vitamin C0.78 mg, potassium 136.41 mg, calcium 89.66 mg, iron 1.61 mg, phosphorus 18.73 mg, nicotinic acid 0.59 mg and flavonoid glycoside. The health food has the health functions of raising immunity, treating diseases and eliminating free radical and resisting senility. Since gynura bicolor grows naturally in south, and is cultivated sporadically and under extensive management, it is difficult to satisfy consumer and market demands because of low yield and poor commercial performance.

Disclosure of Invention

The invention aims to provide a scientific cultivation method of gynura bicolor, which is used for solving the problem of insufficient vegetable supply in spring talking seasons and summer and autumn off seasons. The invention aims to realize the purpose through the following technical scheme that the method for cultivating the gynura bicolor comprises the steps of seedling cultivation, field planting, field management and harvesting, and is characterized by comprising the following steps: 1. seedling raising, namely raising seedlings by a cutting propagation method, cutting 1-2 sections from a robust mother plant, wherein each section is provided with 3-5 leaves, removing 1-2 leaves at the base of a branch, inserting the branch on a seedbed, wherein the seedbed is soil or fine sand, the distance between cutting plants is 6-10cm, the branch is buried in the soil by about 2/3, covering a plastic film after watering, preserving heat and moisture, preserving the heat at about 20 ℃, watering once in 3 days, and surviving for 10-15 days, namely planting seedlings; 2. planting, after selecting planting land, applying 3000kg of decomposed organic fertilizer per mu, deeply turning for 20-30cm, harrowing, making 1-1.2 m high furrows with width of 15cm, planting seedlings with soil for planting in planting, and planting the seedlings with row spacing of 25-30 cm; 3. on the basis of applying enough base fertilizer, 1000kg of thin human excrement or 10-20kg of urea is applied after each harvesting, watering should be carried out in time after each dressing, watering should be carried out in dry weather, but the watering amount is small, and the condition that the soil is dry and wet is suitable is met; 4. harvesting, when the plant height reaches 25-30cm, harvesting the young tips about 15cm, harvesting 2-3 leaves of the root at the first time, growing a new tip at each axilla, harvesting 1-2 leaves at the next time, harvesting once every 10-15 days in spring and autumn, and harvesting once every 20-30 days in summer and winter.

The gynura bicolor cultivated by the method has soft and smooth quality, crisp and tender taste and good commodity, can be harvested all the year round, has the yield more than 2 times higher than that of natural growth, and has better economic benefit.

Detailed Description

Embodiment 1, a method for cultivating gynura bicolor, including seedling raising, field planting, field management and harvesting, is characterized by comprising the following steps: 1. seedling raising, namely raising seedlings by a cutting propagation method, cutting 1-2 sections from a robust mother plant, wherein each section is provided with 3-5 leaves, removing 1-2 leaves at the base of a branch, inserting the branch on a seedbed, wherein the seedbed is soil or fine sand, the distance between cutting plants is 6-10cm, the branch is buried in the soil by about 2/3, covering a plastic film after watering, preserving heat and moisture, preserving the heat at about 20 ℃, watering once in 3 days, and surviving for 10-15 days, namely planting seedlings; 2. planting, after selecting planting land, applying 3000kg of decomposed organic fertilizer per mu, deeply turning for 20-30cm, harrowing, making 1-1.2 m high furrows with width of 15cm, planting seedlings with soil for planting in planting, and planting the seedlings with row spacing of 25-30 cm; 3. the field management is that the gynura bicolor rarely suffers from diseases and insect pests, the management is mainly water-fertilizer management, 1000kg of thin human excrement or 10-20kg of urea is applied after each time of harvesting on the basis of sufficient base fertilizer application, water is timely irrigated after each time of topdressing, and water is irrigated in dry weather, but the irrigation amount is small, and the condition that the soil is dry and wet is suitable; 4. harvesting, when the plant height reaches 25-30cm, harvesting the young tips about 15cm, harvesting 2-3 leaves of the root at the first time, growing a new tip at each axilla, harvesting 1-2 leaves at the next time, harvesting once every 10-15 days in spring and autumn, and harvesting once every 20-30 days in summer and winter.
