Problems solved by technology

Different treatment methods before sowing the Andrographis paniculata seeds have different effects on the germination rate of the seeds. In the above two patent applications, the Andrographis paniculata seeds all adopt the method of warm water soaking, and the germination rate of the seeds still needs to be improved. Furthermore, the above two patents In the application, the Andrographis paniculata are first raised until the seedlings grow to a certain extent and then transplanted into the field, which consumes a certain amount of time, cost and labor

Embodiment 1

[0020] The cultivation method of a kind of corn interplanting Andrographis paniculata provided by the invention is as follows:

[0021] 1. Land preparation

[0022] Machine plowing is used to prepare the land, the row spacing is 65 cm, and the soil is evenly crushed to ensure that the corn seedlings emerge neatly.

[0023] 2. Corn sowing

[0024] On March 16, the corn was sowed in ditches with a plant spacing of 30 cm. When the corn was sown, 20 kg of compound fertilizer with a ratio of nitrogen, phosphorus and potassium of 15:15:15 was applied per mu as the base fertilizer, and then the corn seeds and fertilizer were covered with soil at the same time. 3-4cm. After the corn is sown, spray the herbicide in time before the seeds germinate. Use 50% acetochlor EC 100ml-120ml per mu, add 50kg-60kg of water and spray evenly on the soil surface. If the soil is too dry, spray water first or properly Increase the amount of herbicide mixed with water.

[0025] 3. Corn field managem...

Embodiment 2

[0038] The cultivation method of a kind of corn interplanting Andrographis paniculata provided by the invention is as follows:

[0039] A kind of cultivation method of corn interplanting Andrographis paniculata, wherein, the row spacing of corn is 68cm, the plant spacing is 28cm, the seed coat of Andrographis paniculata is mixed with fine sand before sowing, after removing the waxy layer, soak the seeds in warm water at 43°C for 1.5 days, and mix the seeds with Mix the plant ash and spread evenly between the corn rows. All the other are identical with embodiment 1.

Embodiment 3

[0041] The cultivation method of a kind of corn interplanting Andrographis paniculata provided by the invention is as follows:

[0042] A kind of cultivation method of corn interplanting Andrographis paniculata, wherein, the row spacing of corn is 70cm, the plant spacing is 30cm, the seed coat of Andrographis paniculata is mixed with fine sand before sowing, the waxy layer is removed and then soaked in warm water at 43°C for 2 days, and the seeds are mixed with Mix the plant ash and spread evenly between the corn rows.

Abstract

The invention belongs to the technical field of corn cultivation and particularly relates to a cultivation method for interplanting corn and herba andrographitis. The method comprises the steps: (1) corn sowing: carrying out furrowing and drill seeding on corn according to the corn row spacing of 65cm to 70cm and the plant spacing of 25cm to 30cm, and covering the corn with soil by a thickness of 3cm to 4cm after sowing; (2) herba andrographitis seed treatment and sowing: firstly, mixing herba andrographitis seeds with fine sand prior to sowing so as to scratch seed coats, removing wax coats, then, soaking the seeds with warm water with the temperature of 40 DEG C to 45 DEG C for 1 to 2 days, then, uniformly mixing the seeds with plant ash, and then, uniformly spreading the seeds among corn rows; and (3) field management: carrying out harvesting when shucks of corn become yellow, carrying out harvesting at a budding or flowering stage of herba andrographitis, and reaping whole herbs from overground stem base parts. According to the method, by a corn and herba andrographitis interplanting cultivation mode, natural resources such as light, heat and water are sufficiently utilized, the multiple cropping index is increased, the yield of crops is increased, and the agricultural planting benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of corn cultivation, and in particular relates to a cultivation method for corn interplanting andrographis paniculata. Background technique [0002] Corn is one of the three major food crops and the main raw material for the feed industry. In Guangxi, it is dominated by hills and mountains, with many mountains and few plains, and a large amount of corn is planted. The planting area of ​​corn is second only to rice, and it occupies an extremely important position in the food composition. The traditional planting method is to plant spring corn. Due to the drought in autumn, the land is generally idle after the spring corn is harvested, and the land cannot be used effectively, resulting in waste of resources and low economic benefits. Farmers are not motivated to plant corn. Management-oriented. [0003] As a traditional Chinese medicine, Andrographis paniculata has the functions of clearing away heat and det...
