Abstract

The invention provides a planting method for common vetch crop rotation of organic paddy fields. The method comprises the following specific steps: (1) reaping paddy rice and reserving high stubbles: reserving the high stubbles of 45cm to 55cm of rice straws during paddy rice reaping, threshing reaped rice straw parts, and then, uniformly spreading the threshed reaped rice straw parts into the organic paddy fields; (2) uniformly broadcasting seeds promptly: sowing common vetch promptly in 15 days after paddy rice reaping according to the density of 4kg/mu to 4.5kg/mu; and (3) forming three kinds of ditches to prevent waterlogging: after the common vetch is sown, forming perimeter ditches, transverse ditches and compartment ditches in big fields in a matched manner, and forming the perimeter ditches and the compartment ditches only in small fields, so as to meet the requirements on obvious water drainage and hidden water filtration. According to the method, through reserving high rice stubbles by using principles of ecology, the ecological environment of common vetch (green manure) growth fields is improved, the upright growth of stems and vines of the common vetch is promoted, the unit-area yield of the common vetch is increased, the yield per mu of fresh grass is 2,000kg to 2,500kg and is increased by two times or more compared with that before improvement, the green manuring and field fertilizing actions of the common vetch (green manure) are exerted efficiently, and the organic paddy field is fertilized rapidly.

Description

The implantation methods of Organic Farming Rice Fields crop rotation common vetch

Technical field

The invention belongs to agricultural technology field, is related to the method for organic Rotation in Paddy Field green manure, especially Organic Farming Rice Fields crop rotation The implantation methods of common vetch.

Background technology

" organic rice --- green manure " crop rotation, is Organic Farming Rice Fields culture fertility, regulation soil acidity or alkalinity, improves the soil organism Content most directly effectively agronomic measures and be taken seriously and use.However, crop rotation Green manuring method is different, unit area fresh grass Volume variance is big, and the effect of culture fertility is completely different.

Current Rotation in Paddy Field Green manuring method has 2 kinds：（1）The rice milking stage later stage（Mid or late August）Kind is broadcasted sowing in interplanting Green manure seed；（2）After rice harves（Late September, early October）Green manure seed is broadcasted sowing during wound.

The major defect that above two method is present is as follows：

（1）Green manure seed is sowed in the rice milking stage later stage, one is that sowing quantity is higher, than sowing multiplex kind of 0.5- after rice harves 1kg；Two be emergence rate it cannot be guaranteed that, flooded bubble and 3, rice strain top leaf with the detention of cane angle and field the moon by field ponding The impact of the factors such as disadvantage time length, Seedling emergence rate only 30-40%, green manure Basic Seedling wretched insufficiency；Three is can not to form reasonable height Colony is produced, green forage yield is low, 200-400 kilogram of per mu yield, do not have due infertile field effect；

（2）Green manure seed is sowed when robbing after rice harves, although the drawbacks of overcoming grouting later stage sowing green manure seed, but be accustomed to Property stay short stubble to be unfavorable for the normal robust growth of green manure, rice straw toothing when being harvesting is short（The high 30-40cm of stubble）, green manure vines without Support thing is climbed and lain prone, can only sprawl growth and cannot vertical growth, decreased growth；Two is due to green manure sprawl growth, vines bottom phase Mutual pile-up, stuffy ventilative printing opacity is easily susceptible to rot；Three are that upper grown is prosperous and bottom growth is poor, and green manure growing environment is poor, It is difficult to obtain fresh grass high yield, general per mu yield fresh grass 800-1200 kilogram.

The content of the invention

In order to overcome the defect of prior art, unit area green forage yield is improved, efficiently play green manure green manuring and fertilize the soil and make With Study on Fertilizing Organic Farming Rice Fields, the present invention proposes the implantation methods of Organic Farming Rice Fields crop rotation common vetch.

The technology design of the present invention：Stay high rice stubble to broadcast sowing green manure seed when exactly gathering in Oryza glutinosa, make height stay rice stubble to become green Fertile vines climb the supporter of vertical growth of lying prone, and allow green manure robust growth to obtain high yield.

The technical solution used in the present invention is：The implantation methods of Organic Farming Rice Fields crop rotation common vetch, it is specific as follows：

（1）Harvesting Oryza glutinosa stays high stubble：When mechanically or manually gathering in Oryza glutinosa, rice straw is left and taken into the high stubble of 45-55cm, the rice straw for prescinding Organic Farming Rice Fields field face is uniformly sprinkled into after the threshing of part；

（2）Uniform broadcasting seed when robbing：In 15 days after harvesting Oryza glutinosa, common vetch, mu sowing quantity 4- are sowed when robbing 4.5kg, it is desirable to scatter seeds uniform；

（3）Play " three ditches " pre- prevention against water-logging evil：After planting, it is supporting that ditch, Yao Gou, railway carriage or compartment ditch are enclosed in land for growing field crops to common vetch；Only rise and enclose in little field Ditch and railway carriage or compartment ditch, reach the requirement of " row's open fire, the dark water of filter ".

Beneficial effect：The present invention stays rice stubble with ecological principle height, improves common vetch（Green manure）Growth field is ecological Environment, promotes common vetch vines vertical growth, increases unit area common vetch yield, and per mu yield fresh grass 2000-2500 is public Jin, than more than 2 times of mu volume increase fresh grass before improvement, efficiently plays the effect of common vetch (green manure) green manuring infertile field, and Study on Fertilizing is organic Rice field.

Specific embodiment

The present invention is described in further detail below.

The implantation methods of Organic Farming Rice Fields crop rotation common vetch, it is specific as follows：

（1）Harvesting Oryza glutinosa stays high stubble：Late September to early October, when mechanically or manually gathering in Oryza glutinosa, rice straw is left and taken into 45- The high stubble of 55cm, is uniformly sprinkled into Organic Farming Rice Fields field face after the rice straw part threshing for prescinding；

（2）Uniform broadcasting seed when robbing：In 15 days after harvesting Oryza glutinosa, common vetch, mu sowing quantity 4- are sowed when robbing 4.5kg, asks and scatters seeds uniformly；

（3）Play " three ditches " pre- prevention against water-logging evil：After planting, it is supporting that ditch, Yao Gou, railway carriage or compartment ditch are enclosed in land for growing field crops to common vetch；Only rise and enclose in little field Ditch and railway carriage or compartment ditch, reach the requirement of " row's open fire, the dark water of filter ".

Using crop rotation common vetch of the present invention, per mu can guarantee that the Seedling of common vetch 12-14 ten thousand, go out compared with prior art Seedling rate is greatly improved, and green forage yield increases notable.

The present invention innovative point be：

1st, using rice straw biologic strut function, height stays rice stubble to support green manure vines vertical growth, promotes green manure robust growth；

2nd, the field ecological environment for being adapted to green manure robust growth is created, the restraining factors of green manure high yield are placed restrictions in breakthrough.
