Straw cover new technology

Our province has abundant straw resources, but its utilization rate is not high, waste is serious, and even burning causes air pollution. Since the 1980s, a large number of experimental demonstrations in our province have shown that straw mulching has significant effects on increasing fertility, soil remediation, soil conservation, temperature regulation, and turfgrass in drylands, and can effectively coordinate the irrigated soil moisture and heat conditions and improve crops. The ecological environment is a comprehensive practical agricultural new technology that integrates water-saving agriculture, organic agriculture, and agriculture and ecological agriculture. It is simple and easy for farmers and welcomes them. This technology won the second prize of the Agriculture, Animal Husbandry and Fishery Harvest Award of the Ministry of Agriculture and the Provincial Science and Technology Progress Award.

Increase production and efficiency:

At present, the entire province has an area of ​​about 3.2 million mu. The average yield per mu increased by 8 to 10%, the cost of the project was increased by more than 30 yuan, the soil organic matter was increased by 0.02%, the physiochemical properties were significantly improved, and the winter crop water use efficiency was improved, which had a certain improvement effect on crop quality.

Technical points:

1. Coverage in dry land crops such as wheat, rapeseed, cotton, melons, fruit trees, and vegetables covers one season a year. Autumn and winter coverage are better than those in spring and summer, and autumn and winter are mainly used to cover fields. 2. Straw which can be used for covering includes bean stalk, rape stalk, sesame stalk, rice straw, corn stalk and straw. 3, the amount is generally suitable for 200 kg per acre, "the ground is not exposed white, grass can not be awkward" as a standard, while applying 5 to 8 kg of urea per acre, adjust the carbon and nitrogen ratio, reduce the bacteria and crops between the phenomenon of nitrogen . 4. Coverage: Live crops such as wheat, corn, beans and other crops are planted on the soil surface of the arable land immediately after sowing. After covering, the ditch is ditched and the ditch is evenly spread on the straw. Transplant crops such as rape, Sweet potatoes, melons, etc., first covered and then transplanted; summer broad-ranging crops such as cotton, etc., the last cultivator weeding and fertilizing before covering; fruit trees, tea mulberry and other crops covered after harvest. 5, monitoring the occurrence of field grass damage and pests and diseases. Appropriate area: dry production area in the province.

Precautions:

1. Apply base fertilizer and increase nitrogen fertilizer. Straw

Covering requires the proper amount of nitrogen

Fertilizer to regulate carbon-nitrogen ratio. usually

Coverage of nitrogen fertilizer is better than no coverage

Increase 30% to 40%. 2, control weeds. Controlling weeds is one of the key measures to implement the straw mulching technology. It is required to spray the herbicide after sowing, or to implement cultivator and weed control according to the situation (combined with topdressing). 3, prevention and control of pests and diseases. Straw mulching technology has effectively improved soil structure, nutrient status, and water status, which will inevitably change the original ecological and biological systems of the soil, and will certainly have an impact on the occurrence of pests and diseases.
