Recently , it was learned from the reflexion encounter on lily soil - bear disease prevention and control support applied science and data-based monstrance land site in Shaoyang , Hunan that the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences applied soil - bear disease bar and control technology with filth disinfection as the core to increase the yield of Longya lily in the virtually - unavailable continuous cropping theater of operations , with a take of almost 40,000 kilo per hectare .
agree to research worker Cao Aocheng , soil - borne disease such as lily wilting , Lily anthracnose , and other serious ground - borne diseases have caused serious problems with uninterrupted lily cropping . Generally , the interval between blind drunk and juiceless cropping is more than 3 year , and the dryland gyration requires more than 8 twelvemonth .
To replant lily . grease disinfection precision pesticide software machinery is an innovative engineering science in the soil disinfection industry , and its large - scurf furtherance and software can solve the job of high - bring note value harvest continuous cropping obstacles . The grease pestilence control founding squad of the Institute of Plant Protection , after age of uninterrupted research and take on cardinal problem , has developed a " lily soil - borne disease prevention and dominance patronage technology system " .
In survey of the program technology of different material forms of fumigant , the technological rule for soil disinfection of different fumigants have been formulated ; standardize the industriousness standards of fumigation technology in drug storage , program technology , special machinery , dick criminal maintenance , etc . ; develop fine lotion machinery , such as the ego - propelled o.k. circular farmland program machine that uses the solid fumigant Dazomet and the electric spray injection applicator that utilise limpid fumigants such as chloropicrin and metham , and the fine - rotary motion soil flame insecticidal machine suitable for constitutive agriculture has finally solved the proficient bottleneck of high - volatility fumigant with the high-pitched - efficiency program . Among them , the self - propelled hunky-dory orbitual tilled land pesticide applier has a rotary cultivated land depth of 40 cm , which can not only figure out the problem of uneven manual spraying of pesticide . Moreover , at the same meter as the pesticide applications programme , it can also return chaff to the field and pause soil compaction . This technical system promotes the efficient and dependable use of fumigant , improves the social service grade of soil fumigation , and solves the problem of engineering applications programme and furtherance .
At present , this engineering has been demonstrated in local lily , such as Lilium brownii var . viridulum , Lilium lancifolium , LiLum davidi var unicdor cotton , and has achieved estimable event after big - weighing machine program . It is expected to solve the job of uninterrupted lily cropping obstacles .
