Problems solved by technology

Houttuynia cordata has always been a wild plant, and it has been artificially cultivated since the early 1940s. However, due to the low temperature in winter, the growth of the aboveground part of Houttuynia cordata cannot be guaranteed, so the supply of Houttuynia cordata is in trouble

experiment example 1

[0021] Experimental Example 1: Comparison experiment between greenhouse planting method (see Example 1) and bare land planting method

[0022] 1. The environmental temperature and humidity and the growth effect of Houttuynia cordata were compared between the greenhouse planting method planted in winter and the bare land planting method. The results are shown in Table 1.

[0023] Table 1: Comparison of temperature, humidity and growth effect of greenhouse planting methods

[0024]

[0025]

[0026] The above table shows: ①The temperature of greenhouse planting is relatively constant. ②Houttuynia cordata grown in greenhouses grows faster than Houttuynia cordata planted in bare ground at the same period, the plant growth rate is faster, especially the growth rate of plant height above the ground; at the same time, the growth of fresh weight per plant is also higher.

[0027] 2. Comparison of the growth period of Houttuynia cordata planted in greenhouses and bare land

experiment example 2

[0045] Experimental example 2. Screening experiment of different technical parameters under the condition of Houttuynia cordata greenhouse planting

[0046] 1. Comparison of different planting modes of Houttuynia cordata in greenhouses

[0047] When sowing, the greenhouse experiment adopted three planting modes: ① greenhouse; ② greenhouse + plastic film (see Example 1); See Table 5 for the comparison results of the emergence speed of Houttuynia cordata in different planting modes.

[0048] Table 5: Comparison of emergence speed of Houttuynia cordata with different planting methods in greenhouses

[0049]

[0050] Note: Letters represent a statistically significant 5% difference level.

[0051] From the emergence speed of the greenhouse planting mode in the above table, it can be explained that the third type (greenhouse + plastic film + lamp) is slightly better than the second type (greenhouse + plastic film), but there is no significant difference between the two; ) is ...

Embodiment 1

[0086] (1) Greenhouse construction: including horizontally distributed bow-shaped or bow-like beams, longitudinally distributed cross bars or bars; transparent PVP film with a length of 25-30m, a width of 5-6m, and a height of 3-3.5m; the main beam: Bamboo; frame: steel pipe; scaffolding on the nursery ground, covering with film, and forming the main body of the greenhouse;

[0087] (2) Planting

[0088] ① Nursery preparation: select pH 5.0-6.5, organic matter content 22.78g / kg, total nitrogen 1.19g / kg, available potassium content 120.32mg / kg, available phosphorus content 43.63mg / kg

[0089] ② Soil preparation: After plowing the selected nursery before sowing (September-October), divide the compartments according to the following distance, the width of the compartment is 5-6m, the width of the trench is 1-2m, and the depth is 0.4-0.5m. After the fertilizer is applied, the soil on the car surface is smashed and leveled;

[0090] ③ Sowing: Select high-quality Houttuynia cordat...

Abstract

The invention relates to a method of planting herba houttuyniae in a greenhouse, which includes: firstly, setting up a greenhouse; secondly, using sandy soil with 5.0-6.5 pH, 20-25g / kg organic content, 1.0-1.5g / kg total nitrogen, 100-150mg / kg content of quick-acting potassium and 40-50mg / kg content of rapidly available phosphorus for planting, scattering high-quality stems of herba houttuyniae with one to two bud eyes on a nursery according to a seeding quantity of 40-50kg / mu, wherein the planting is available all year around; and thirdly, performing management, including temperature control, irrigation, topdressing, weeding and control of pest diseases and insect pests. Using the method can especially solve the problem of partial supply insufficiency of fresh herba houttuyniae lands in winter and spring (from November to May), so that the part of herba houttuyniae can grow normally in the herba houttuyniae lands in winter and spring, the growth period of the greenhouse planted herba houttuyniae is shortened, and the yield is evidently higher than that planted in bare lands.

Description

technical field [0001] The invention relates to a method for planting Houttuynia cordata, in particular to a method for planting Houttuynia cordata in a greenhouse. Background technique [0002] Houttuynia cordata Thunb (Houttuynia cordata Thunb), scientific name Houttuynia cordata Thunb, belongs to the genus Houttuynia cordata Thunb, is a perennial herbaceous plant. Houttuynia cordata is mainly eaten as vegetables with tender stems, leaves and underground stems. The whole plant can be used fresh or dried as medicine. It has been officially identified by the Ministry of Health as one of the resources with great development potential that is "both medicine and food". , has received increasing attention. Houttuynia cordata has always been a wild plant, and it has been artificially cultivated since the early 1940s. However, due to the low temperature in winter, the growth of the aboveground part of Houttuynia cordata cannot be guaranteed, so the supply of Houttuynia cordata is...
