Embodiment 1

[0062] A method for direct seeding drip irrigation with biodegradable plastic film for dry farming rice, comprising the following steps:

[0063] 1. Choose a place

[0064] (11) Choose a plot with flat terrain, fertile soil, no phytotoxicity to rice in the previous crop, and drip irrigation equipment under the film;

[0065] (12) The soil pH of the plot shall not exceed 7.5, and the content of sulfate shall not exceed 0.3 wt%;

[0066] 2. Variety selection

[0067] Choose the locally grown dry-fed rice variety, which requires 7 days earlier in the growth period, better rice quality, stronger resistance and higher yield than the local transplanted rice variety;

[0068] 3. Seed soaking

[0069] (31) during sun-drying, remove glutinous rice, grass seeds and sundries, then sun-dry the seeds for 3 days (improve the germination rate and germination potential of seeds) under the sun on a sunny day, enter step (32) after completion;

[0070] (32) Seed selection with brine

Abstract

The invention belongs to the technical field of planting, and particularly relates to a dry farming rice biodegradation mulching film direct seeding and drip irrigation method. The invention discloses a dry farming rice biodegradation mulching film direct seeding and drip irrigation method. The method comprises the following steps: 1, land selection; 2, variety selection; 3, seed soaking; 4, soil preparation; 5, fertilizing; 6, sowing and film covering; 7, dripping water; 8, weeding; 9, timely harvesting. The dry farming rice biodegradation mulching film direct seeding drip irrigation method has the advantages that compared with conventional rice cultivation, leaf surface transpiration, water surface evaporation and underground leakage are reduced, and water can be saved by 70%; (2) the drought growth of the rice in the seedling stage is favorable for ensuring rooting and seedling hardening of the rice seedlings, and the drought resistance and lodging resistance are enhanced; and (3) the field operation frequency and labor intensity are reduced, the operation cost is reduced, and the links of shed covering, seedling raising and field steeping, harrowing and rice transplanting are omitted.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a direct seeding drip irrigation method for dry rice biodegradable plastic film. Background technique [0002] Agricultural plastic film has become the fourth most important material in agricultural production after seeds, chemical fertilizers and pesticides. The technology of plastic film mulching has led to the improvement of agricultural productivity and the great change of production methods in my country. Data from the National Bureau of Statistics shows that the use of plastic film increased from more than 300,000 tons in 1993 to 1.437 million tons in 2017, and the area covered by plastic film increased from 86 million mu in 1993 to 279 million mu in 2017. The application area has expanded from the arid and semi-arid areas in the north to the high-altitude mountainous areas in the south, and the types of crops have also expanded from commercial crops to bulk fo...
