Zenia insignis and dalbergia odorifera mixed afforestation method in stony desertification region

ActiveCN105393892AImprove the ecological landscape effectReduce cost inputClimate change adaptationAfforestationSoil conservationRevegetation
The invention discloses a Zenia insignis and dalbergia odorifera mixed afforestation method in stony desertification regions. The method comprises cleaning a mountain and preparing land, processing seedlings, afforesting in a mixed manner, and performing tending management. The method specifically comprises: in autumn in the previous year of afforestation, performing manual cave-shaped land preparation, selecting Zenia insignis container seedlings of 5-8 months and dalbergia odorifera container seedlings which are older than or equal to one year old to afforest, using a star-like uneven-aged mixed plantation method, plantation density of a mingled forest being 1900-2600 plants/hm2, after afforestation, weeding, applying fertilizer, and tending. The method breaks a problem that a Zenia insignis pure forest has stony desertification in a seasonal manner because of fallen leaves in winter, and makes Zenia insignis and the dalbergia odorifera muturally promote growth, so as to improve vegetation coverage of stony desertification mountain areas, improve soil, and enhance water and soil conservation effect. The method maintains soil fertility, promotes growth of rare tree dalbergia odorifera trees in height and improves trunk quality, reduces investment in manual trimming of the dalbergia odorifera and arranging trunk auxiliary supports, accelerates vegetation recovery process in the stony desertification regions, and increases income of mountainous area people. The method has good social benefit and ecological benefits.

Weed preventing and controlling method for sweet sorghum

InactiveCN105875577AReduce cost inputGrowth inhibitionWeed killersWeedSweet sorghum
The invention provides a weed preventing and controlling method for sweet sorghum. The weed preventing and controlling method is characterized in that at the period of spring sowing, a weed killing agent with the mass concentration of 44-56% is uniformly applied on the soil before sowing, so that not only is the weed killing effect better, but also the hazard degree for planted crops is low. A mulching film is laid immediately on soil using the weed killing agent, and is used for preventing reduction of the pesticide effect due to volatilization caused by illumination or decomposition of the weed killing agent; and the result shows that the weed killing effect is good when the dosage of the yibingcao-you weed killing agent with the concentration of 50% is 3750ml/hm<2>, and the influence on growth and development of the sweet sorghum for forage use is less. The weed preventing and controlling method provided by the invention has the advantages that the complete suppressing action on growth of weeds in the sweet-sorghum field is achieved, and the preventing effect can reach 100%; and the weeds such as amaranthaceae, gramineae and chenopodiaceae in the sweet-sorghum field can be effectively prevented and killed. The weed preventing and controlling method provided by the invention is a feasible technical measure adapting to the development requirement in the modern agriculture, can save the cost investment in production of the sweet sorghum and relieve the labor intensity, and plays an important role in production of the sweet sorghum.
