Problems solved by technology

[0005] In view of the defects of the existing chemical weeding technology, the problems of traditional straw returning to the field in preventing and controlling weeds, and the contradiction between soil fertilization and crop production, the purpose of the present invention is to provide wheat ecological weed control planting that comprehensively utilizes rice stubble and green manure The method and facilities. In the method, milk vetch is sown before the rice is harvested. After the rice is harvested, the straw is concentrated in the ditch to decompose, and at the same time, the wheat is drilled in the field, so as to realize soil fertilization and weed control, and ensure crop yield and quality safety. At the same time, reduce the use of chemical fertilizers and pesticides

Embodiment 1

[0043] The first object of the present invention is to provide a kind of wheat ecological control grass planting method that comprehensively utilizes rice stubble and green manure, and described method comprises the following steps successively:

[0044] Step (1): sow milk vetch before rice harvest;

[0045] Step (2): After the rice is harvested, use the self-propelled straw bundling and sowing machine to bundle the straw into straw bundles, open ditches in the paddy field and gather the straw bundles in the ditch to decompose;

[0046] Step (3): At the same time, the self-propelled integrated straw bundling and sowing machine performs wheat drilling in the field.

[0047] As a preferred embodiment, the method for wheat ecological grass control planting comprehensively using rice stubble and green manure provided by the present invention is further set as follows: in the step (1), the time for sowing milk vetch is 5-10 days before rice harvest.

[0048] As a preferred embodim...

Embodiment 2

[0068] A wheat ecological grass-control planting method that comprehensively utilizes rice stubble and green manure. In this method, milk vetch is sown before the rice is harvested. After the rice is harvested, the straw is concentrated in the ditch to decompose, and the wheat is drilled in the field at the same time, which can realize soil fertilization and weed control. While ensuring crop yield and quality safety, it can achieve The reduction of chemical fertilizers and pesticides includes the following steps:

[0069] (1) 5 to 10 days before the rice harvest, choose sunny weather, spread milk vetch Ningbo seeds evenly into the paddy field at 2.0 kg / mu, and the organic matter content of the paddy field soil is 2.13%.

[0070] (2) The rice is harvested by Kubota 988 full-feed harvester, and the rice straw is quickly rotted through the self-made straw ditch - the integrated planting machine is sprayed with decomposing agent - straw picking - bundling - wheat sowing - ditching...

Embodiment 2

[0076] A control experiment was carried out on the land under the same conditions, and the soil organic matter content was 2.13%. Use herbicides to seal the land, use Sumai 188 for wheat, and the sowing rate is 13 kg / mu. The rice straw is quickly rotted through the self-made straw ditch - the integrated seeding machine is sprayed with a decomposing agent - the straw is picked up - bundled - the wheat is sown - the ditch is opened and then put into the drainage ditch. The NPK chemical fertilizer is pure nitrogen 12 kg / mu (the whole growth period, wherein, base fertilizer: topdressing = 6:4), P 2 o 5 5 kg / mu, K 2 O 6 kg / mu, phosphorus and potassium fertilizer was applied as base fertilizer at one time. Herbicides were sprayed again at the jointing stage of wheat.

[0077] Results: The yield of the wheat field was 286 kg / mu, the weeds in the wheat field were 68 plants / square meter in 2016, and the weeds in the wheat field were 76 plants / square meter in 2017. Compared with the...

Abstract

The invention discloses a wheat ecological grass control planting method for comprehensively utilizing rice stubble and green manure. The method comprises the following steps of (1) sowing milk vetchbefore rice harvesting, (2) bundling rice straws to from rice straw bundles by using a self-propelled straw bundling and sowing integrated machine after the rice harvesting, ditching a rice field andplacing the straws in field ditches for returning and decomposing, and (3) performing wheat sowing in lines in the field by using the self-propelled straw bundling and sowing integrated machine. According to the method, by sowing the milk vetch before the rice harvesting, carrying out concentrated ditch returning and decomposing on the straws after the rice harvesting and performing wheat sowing in lines in the field, the soil fertilization and weed control can be achieved, and the reduction of fertilizers and pesticides is achieved while the crop yield and quality safety are ensured.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation technology and equipment, and in particular relates to a wheat ecological grass control planting method and facilities for comprehensively utilizing rice stubble and green manure. Background technique [0002] For the control of field weeds, chemical control of isoproturon, fenoxaprop-ethyl, clodinafop-propargyl, etc. is usually used in production. In recent years, with the frequent occurrence of food safety issues and ecological crises, the Chinese government has gradually realized that the excessive use of pesticides is harmful to food safety and environmental protection. Action Plan", in December 2015, the Ministry of Science and Technology set up a special science and technology project of "Reducing Fertilizer and Pesticide Application and Increasing Efficiency" to implement nationwide pesticide reduction. In addition, the long-term overreliance on chemical herbicides has also led to...
