Van-type no-tillage improved high-yield cultivation method of cold mud field

Abstract

The invention discloses a van-type no-tillage improved high-yield cultivation method of cold mud field. According to the method, the van width of the gully field with serious gleying can be about 3.0m; the van width of the field with light gleying can be 4.0-5.0m or more; the van length can be determined according to the field shape; the width of the van ditch is 30cm and the depth is 20-30cm; the ditch penetrates through the whole rice field; the rice plantation rule adopts wide and narrow row spacing plantation, namely, the narrow row is 20-23cm and the wide row is 43.33-50.00cm; a drainage ditch is formed between two vans in order to drain water; the dug soil can be uniformly paved on the whole van along the length direction of the van in order to ensure that the van is 15-20cm higher than the water level; the fertilizer application method is as follows: based on the application of proper nitrogen-phosphorus-potassium fertilizer, 100kg of silicon-calcium fertilizer applied in per mu is used as a modifier in order to regulate pH value and redox potential of the soil in winter paddy field. With the adoption of the cultivation method, rice yield in one season can be improved by more than 5%.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a box-type no-tillage improved high-yield cultivation method in a cold mud field. Background technique [0002] Cold mud field is an effective farming system that uses natural precipitation scientifically in hilly and mountainous rice areas that lack water conservancy projects and supporting irrigation conditions to ensure smooth planting and stable and high yield of rice. It has scientific and economical use of natural precipitation resources; fallow soil, fertilization Soil fertility; cropping crops earlier, alleviating labor tension and water conflicts; preventing soil erosion, improving the ecological environment; supplementing groundwater sources, reducing geological disasters; comprehensive utilization, improving the efficiency of cultivated land, etc. Factors constraining the low yield of paddy soil in cold mud fields include poor soil structure, low water and soil t...

Problems solved by technology

Manual ridges are labor-intensive. Generally, it takes two or three times to complete the ridges. After transplanting the seedlings, it is necessary to clear the ditch and support the ridges 1 or 2 times, which is labor-intensive and requires high technology.

Due to these defects and deficiencies in this technology, especially the current soaring labor price in the country, it is very difficult to promote and apply this technology.
