(artificial broadcast and mechanical bunch planting) plantation, promotes Rice Production force-saving synergistic in a manner of two kinds of Rice Croppings.
Raising rice seedlings machinery is inserted planting patterns and is developed comparatively fast in developed area, northeast rice region peace Yuanping City Ba Qu, and
Area underdeveloped, hills area and mountain development are slower.Directly seeding rice mode is proved through production practices, is not only suitable for educating
Seedling machinery inserts the area of planting patterns, and the hills or mountain area of suitable for producing condition difference, force-saving synergistic effect are fairly obvious.
Whether directly seeding rice production method success or not, lodge depending on Later Stage of Rice, and rice lodging control depends on sowing
When seed rice driving depth, how much seed rice driving depth be directly related to rice seedling, and then influences direct seading rice yielding Populations
Establish with lodge number.Since ecology is gradually restored in recent years, when annual spring rice growing and when sparrow frequent activity.
It is also the effective ways for preventing sparrow from endangering that seed rice enters mud deeply enough.Therefore, the strong good rice varieties of native power are pushed up in selection, by it
It is sown into soil, is one of successful key technique of direct seading rice production method.But up to the present there are no one kind
It can be used in identifying the specific method of rice varieties top soil ability, the Ministry of Agriculture and the provincial Crop breed audit committee are authorizing
