Embodiment 1
[0031] A kind of rush stubble late rice waste grass covering ecological direct seeding method, it comprises the following steps:
[0032] (1), preparation before sowing:
[0033] ①, rush field preparation
[0034] a. For weeding in the rush field, use herbicides such as Sushou, Guoer, and procaojing for weeding. Do not use chlorsulfuron herbicide, otherwise the residual chlorsulfuron in the soil will affect the growth of inter-sowed late rice seedlings. b. Drainage and irrigation in the rush field When the rush field is placed in the field, dig the surrounding ditches and field operation ditches, and dredge and clean the surrounding ditches and operation ditches before the rush nets are hung. 7 to 10 days before rush harvest, clear the weeds on the fields and dig deep ditches;
[0035] ②, seed preparation
[0036] a. Variety selection, choose a variety with compact plant type, strong stem, medium tillering ability, high fertilizer resistance, more green leaves in the later ...

Abstract
The invention relates to a rush stubble late rice waste grass covering ecological direct sowing method, comprising the following steps of: 1. preparation before sowing; (1) preparation of a rush field: a. weeding in the rush field, b. executing drainage and irrigation in the rush field; (2) seed preparation: a. seed selection, b. seed treatment; 2. seed sowing; 3. late rice management after rush harvest; (1) opening up nitches and gutters; (2) covering waste grass and weeding; (3) irrigating in the way that after irrigation, the water is immediately released, and after the soil begins to turn dry, irrigation is executed for a second time, and then the water is released again; (4) after the trefoil stage of seedlings, executing field rest, fertilization, weeding and irrigation, and preventing plant diseases and insect pests; (5) in the fourth-leave stage of the seedlings, regulating the density of the seedlings and irrigating the seedlings; (6) in the fifth-leave stage of the seedlings, executing weeding and irrigation; (7) when the top second leaf of the rice appear, executing fertilization; (8) from the booting stage to the heading and flowering stage of the rice, executing irrigation and preventing plant diseases and insect pests; and 4. harvest. The method is characterized by no generation of smoke, no influence on the local ecological environment, the aviation safety of nearby airports, and sowing time, low cost and high late rice yield.
Description
Technical field: [0001] The invention belongs to the field of agriculture, and in particular relates to an ecological direct-seeding method for covering late rice waste grass with rush stubble. Background technique: [0002] Rush is a traditional economic crop, and its processed products such as tatami mats are exported to Japan and other places. At present, after the qualified rush is harvested in the rush production area, about 400-500kg of unqualified rush is discarded per mu. Residents of the city suffered from smoke damage, which seriously affected the local ecological environment, and also brought safety hazards to the nearby airport aviation. Furthermore, the traditional planting method of rush stubble late rice needs to go through steps such as seedling raising, plowing, whole field and transplanting, which increases labor and labor costs; and after plowing, the original fertile layer in the field is turned over In the inner layer, if there is no top-dressing, it w...
