Embodiment 1

[0048] A high-yield cultivation method for paddy field irrigation and cultivation of mountain bar rice, comprising the following steps:

[0049] (1) Strong Seedling Cultivation of Shanlan Rice by Water

[0050] 1. Seed treatment

[0051] Sun-drying: spread the seeds thinly on the sun-drying mat or concrete floor, sun-dry the seeds for 1-2 days, and turn them frequently to make the seeds dry to the same degree.

[0052] Seed selection: Use yellow mud water or salt water to select seeds, and choose pure, plump, and neatly germinated seeds.

[0053] Seed soaking and germination: Seed soaking for 48 hours at a water temperature of 30°C, and the soaking time should be extended appropriately at low temperatures. Disinfection and soaking are carried out in combination, using a disinfectant combined with soaking and disinfection. When soaking the seeds, turn them up and down 2-3 times a day, and then rinse them twice with clean water.

[0054] 2. Semi-dry seedling raising in open fie...

Embodiment 2

[0070] A high-yield cultivation method for paddy field irrigation and cultivation of mountain bar rice, comprising the following steps:

[0071] (1) Cultivation of strong seedlings in dry paddy fields of mountain bar rice

[0072] Dry seedling raising is a method of raising seedlings under dry land conditions, without establishing a water layer at the seedling stage, and mainly relying on soil moisture and watering to cultivate strong seedlings. Plastic floppy disks can be used for dry seedling raising. Wherein the links such as seed treatment, seed soaking and accelerating germination are with embodiment 1, and other steps are as follows:

[0073] 1) Seedling field selection and seedling box specifications: choose vegetable gardens or paddy fields close to water sources, convenient for irrigation and drainage, fertile, loose soil, and free of pests and diseases as seedbeds. Seedling box specifications: make the seedbed 1.4-1.7 meters wide; make 25-30cm×25-30cm drainage ditc...

experiment example

[0090] The variety of Shanlan rice used in the test was Baishashanlan (partially japonica glutinous rice, yellow-hull inner white), and three cultivation methods were designed: paddy cultivation (paddy cultivation, P ): i.e. the method of the present invention; rice-straw mulching (rice-straw mulching, RS): measures are the same as that of dry planting, 5-7 days after transplanting, straw is covered, and the straw material is taken from the dry rice straw newly cut by farmers; Upland cultivation (U): The rice fields are naturally sun-dried without watering from the transplanting stage without artificial irrigation.

[0091] Measurement items and methods:

[0092]The tiller dynamics were investigated every 10 days from transplanting to effective tiller termination period, and the plant chlorophyll content (SPAD) and peroxidase (Peroxidase, POD) were investigated 1 day before transplanting, tillering stage, booting stage, heading stage and mature stage respectively. Physiologic...

Abstract

The invention provides an upland rice paddy field irrigation planting high-yield cultivation method which mainly includes the steps of seedling strengthening culture, paddy field transplanting, paddyfield transplanting fertilization, water management, upland rice harvesting, drying and the like. An upland rice water cultivation mode is adopted, the original dry cultivation mode of upland rice isbroken through, the degree of water stress to the upland rice can be relieved, weed covering degree is reduced, the total output of the upland rice is increased by 267.44% as compared with that of a common dry cultivation mode, the number of panicles per hole, the number of grains per panicle and ripening rate are very significant in difference in different cultivation modes, and the number of panicles per hole, the number of grains per panicle and the ripening rate of paddy field irrigation planting are larger than those of the common dry cultivation mode. In addition, in the paddy field irrigation planting process of the upland rice, and water can be saved by paddy field dry cultivation seedling strengthening culture and paddy-upland alternating optimal water management technology of field management. By the method, the planting area of the upland rice can be effectively enlarged, and germplasm resources of the upland rice are protected and used.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a high-yield cultivation method for irrigated paddy field rice cultivation. Background technique [0002] Shanlan rice (a kind of upland rice) is a kind of upland rice explored by the Li and Miao people in Hainan through long-term production practice. Shanlan rice is currently cultivated in small areas in mountainous areas, and its cultivation method is single, mainly traditional slash-and-burn cultivation. This method of planting damages the environment. In addition, most of the plants are planted on sloping land. The rainy season is likely to cause soil erosion. In recent years, in order to protect the ecological environment of mountainous areas, local governments have banned burning mountains and deforestation. They can only be planted on the original agricultural land, and the area is limited. Coupled with the low yield and benefit of planting in mountainous areas,...
