Very familiar to the friend of yam country, want the season that harvests to yam again immediately, a lot of planting after establish door perhaps is staying to sell fund more, eat, metropolis choice stores yam. But make kind of many establish door reaction had encountered such problem, the yam that stores namely then has cankered case. If very apparent yam is cankered can reduce farmer earnings, so the issue came, how should farmer friend prevent and cure does yam store the cankered problem in the process? We share pertinent question and measure of prevention and cure today.
Decay happens to basically have between yam storage life the following 4 reasons cause:
A damage
Yam is collected receive a process to be dug mediumly, touch, press the cut such as the injury, suffer the infection of the bacteria the most easily, in high temperature tall wet ventilated not day of the 4~7 below the environment of free is OK and cankered. Yam is optimum the temperature that store is 10-15 ℃ , humidity 80%-9% , lowest of the quantity that contain oxygen 5% , temperature sprouts high, temperature became low easy freeze injury.
B yam freeze injury
Before yam is storing during if be in microtherm,the circumstance of 8 Celsius falls, metabolism can be destroyed. In 10~15 the day is controlled after yam freeze injury, light person cuticular decay, the person that weigh decays entirely. If yam harvest slants late or effect of yam cellar heat preservation differs metropolis aggravate yam to decay.
C yam is wet kill
If field rainwater is overmuch,yam is harvesting later period, or yam has been drenched by rainwater, yam water content is overmuch, yam physiology function is destroyed, the temperature after entering store sth in a cellar or pit lifts quickly bring about yam respiration to strengthen cause decay thereby. Or the water content inside potato cellar passes to also can cause yam to decay greatly.
D yam breed
Partial delicacy feeds yam breed to not be able to bear or endure store, if store,can cause yam decay. Because this is cultivated door whether should store yam, yam breed is very important.
Understood the main reason that causes yam decay, cultivate a precautionary measures that should have specific aim only to be able to ease the problem with cankered yam.
Library of 1 constant temperature is saved
This is current the most scientific also be the safest store method. Big to growing an area, store the amount is cultivated more door applicable. Constant temperature library can adjust artificially the temperature inside the library and humidity, maintain temperature spend in 10~15, humidity is in 90% the left and right sides, it is to store yam first-rate environment.
2 cellar are saved
This is the country is the most commonly used store method. Yam stores optimal temperature is controlled in 15 degrees, temperature crosses tall yam to sprout easily, temperature crosses low incidental freeze injury to reduce quality. Because as it happens of temperature of this country cellar spends the left and right sides in 10~15, suit to store very much so yam. The farmer is cultivated door after be being harvested in yam, air basks in 3~5 Queen of heaven, with branny carapace or corn portfolio outfit, branny, a yam, with layer yam, want to be separated with branny carapace, it is better to take some of land conditionally, ordinal yard is nice can. Perhaps issue the fine sand that an air basks in in cellar bottom, yam ordinal and statified the yard is nice, notice number of plies is not overmuch, should stay have ventilated room. L
3 paper box is saved
To consumer because yam amount is little, the city digs cellar possibly also to save, because this suggests to use case of a paper or box of have enough to meet need, had surrounded yam air with paper first, next ordinal it is good to put box internal code, depositing half an year is no problem. Notice yam does not want skin to have.
Store to yam technology, if everybody has good proposal,can leave a message share.
