Sudan grass is one kind produces the annual herb in Africa formerly. Our country has been introduced before found a state cultivated, this grass is lax to edaphic requirement, mix in weak acid spend salinized soil soil gently to go up to be able to grow. After spring sows, xian Cao can harvest Frost's descent around all the time, it is pig, ox, sheep, horse, hare, fish the high grade succulence that wait, make hay still can regard the wintry lay aside of domestic animals as feedSudan grass although adaptability is very strong, strong acid of if it were not for, alkali and can cultivate quicksand, but the most fundamental management or cannot little. The edaphic management before cultivating should notice the following: 1, because Sudan grass is crop happy fertilizer, break up in soil sufficient base fertilizer must be applied before ploughing, mu apply farmhouse fertilizer 70 ～ are controlled 80 loads, 15% - 15% - the NPK of 15% is compound fat 80 jins, the urea of 46% 30 jins, in combining farmland to turn over be buried, agrarian deep not less than 25 centimeters.
2, turn over the soil after ploughing more loose, the gap of slimy piece is bigger, can make smooth with a rake plus at the back of the tractor, can make flat range already, can aperture of squeezing ramming clod, prevent to sow to be shown from time to tome seam seed.
3, seasonable ditch, bedding wants after plot rectifies smooth, squeezing ramming, farmland area is general make it is 2 meters wide, grow the lot that is not restricted, channel of moisture in the soil should leave a few more greatly, make sure catchment is smooth, after rain not seeper.
Above 3 o'clock is Sudan grass before cultivate, edaphic management field needs watchful place, hope to be able to be helped somewhat to everybody.
