(3) sugar grass is except tiller
In sugar grass field management, sugar grass removes the link that removal of tiller bud is most critical, and wherein alcohol type sugar grass and feeding type sugar grass are the kinds of two different purposes, and the requirement except tiller is different; Type sugar grass used by alcohol, carry out before the shooting stage 2-3 time except tiller work, retain trunk diameter growth, be conducive to ventilating and illumination in sugar grass process of growth, for sugar futures after stem stalk accumulation and stock significant; Feeding type sugar grass, as long as the planting density of controlling well, can remove tiller 1-2 time, no longer can remove tiller later, so both can keep certain population density, total the biomass that can improve again before jointing.
(4) other field management of sugar grass
Other field management of sugar grass also comprise
Break and harden: harden in case of precipitation is formed before sugar grass emerges after broadcasting, be unfavorable for coming up, should abolish in time and harden.
Pour water: sugar grass drought resistance is extremely strong, but in order to obtain high yield, must pour water according to local climate condition and the stage of development of the plant in good time.Seedling stage generally need not irrigate, and after jointing, should water 3-4 time according to precipitation event and plant growing way.
Topdressing: in the shooting stage according to field growing way, impose 1-2 fertilizer in conjunction with pouring water, executing pure N5-7 kilogram (urea 10-15 kilogram) for every mu at every turn.
, there is aphid, should prevent and treat early in the extermination of disease and insect pest: sugar grass pol is high, is subject to aphid damage, sugar grass is irritated to organophosphorous pesticide, the pesticide controls such as available decamethrin, cypermethrin or matrine.When finding that there is snout moth's larva harm lobus cardiacus, select decis, sumicidin prevents and treats; After sugar grass heading, snout moth's larva rises to fringe portion and causes harm, and available above-mentioned agricultural chemicals carries out emphasis spraying to fringe portion.
(5) gather in the crops:
Alcohol type sugar grass reaches maximum in booting to Nutrient matter at heading stage, is suitable harvest time.Feeding type sugar grass can according to the climatic characteristic of zones of different, and when plant to be planted grows to 1.5-2.0 rice, distance ground 15-20 centimeters cradle once, now in stem stalk cellulose and hemicellulose level low, protein content is higher, and does not affect the palatability of cattle and sheep.
