Embodiment 1

[0012] Embodiment 1 Transplanting the method of paddy field wormwood mulching control weeds and reducing medicinal fertilizers

[0013] Utilizing the insect repellent and bactericidal properties of Artemisia plants in the Compositae family, choose wild artemisia, Artemisia annua, Artemisia annua and other Artemisia plants that are easy to collect locally, and use 7.5-15 tons per hectare (500-2000 kg per mu) 7-10 days after rice transplanting, directly cover the wormwood between the rows of rice seedlings, step into the mud with your feet, and cover the field with wormwood to suppress the new weeds in the rice field, inhibiting the normal growth of weeds, and at the same time the wormwood Rotten in the mud to become green manure, providing nitrogen, phosphorus, potassium fertilizer elements and organic matter, which can replace all or part of the application of herbicides and chemical fertilizers, and can still ensure the control effect on paddy field weeds and high and stable r...

Embodiment 2

[0017] Embodiment 2 Field Artemisia weed control test effect

[0018] Select 2 sites of transplanted rice fields in the Yunnan plateau rice field, each site of 5-20 mu of experimental field, as the project research field. Carry out experiments on the amount of coverage of Artemisia plants and the effect of chemical fertilizers and herbicides on field weed control, experiments on the best coverage time of Artemisia plants, and comparative experiments on the dosage of main plants of Artemisia genus. By investigating weeds, rice growth status and yield, paddy soil organic matter, available phosphorus, and available potassium, the inhibitory effect and effect of wormwood mulch on transplanted rice field weeds, the relationship between wormwood mulch and soil organic matter growth and decline, and yield , Artemisia mulch paddy field and coordination technology of rice cultivation measures. The test results are shown in Tables 1-3 below:

[0019] Table 1 The results of field weed ...

Abstract

The invention provides a method for replacing medical fertilizers by transplanting wormwood from a rice field to cover and control weeds. The method comprises the steps of directly covering the rows of rice seedlings with 7.5 to 15t of wormwood per hectare after 7 to 10 days of transplanting of the rice seedlings; pressing into mud with feet. According to the method, the wormwood covers the surface of the rice field in which the rice seedlings are transplanted, and thus the obvious effects that the weeds in the rice field can be controlled, the fertilizer is increased, the rice seedlings are promoted to grow, and the output is increased, can be achieved; the wormwood can replace 100% of chemical fertilizer and 100% of herbicides, and the rice output is kept the same as the rice employing the chemical fertilizer and herbicide.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for transplanting paddy fields with wormwood to cover weed control and reduce medicinal fertilizer replacement. Background technique [0002] In the process of rice cultivation, various chemical fertilizers and herbicides are often used, which not only increases the cost of rice cultivation, but also has the problem of environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for transplanting wormwood in rice fields to cover weeds and reduce medicinal fertilizers, aiming to solve the problems caused by the need for additional chemical fertilizers and the use of herbicides in rice planting. [0004] The present invention is achieved in this way, a method for transplanting rice fields with wormwood to cover weed control and reduce medicinal fertilizers, comprising the following steps...
