This invention discloses a method for rapid propagation of *Taxobacterium tumefaciens* tissue culture using a solid-liquid alternation approach. The method includes: pre-treating young stem segments (3-4 cm) from *Taxobacterium tumefaciens* mother plants as explants; inoculating the pre-treated explants into an adventitious bud induction medium for induction culture; inoculating the induced adventitious buds into a proliferation medium for proliferation culture to obtain clustered buds; transferring the clustered buds into a bud strengthening medium for primary bud strengthening culture; and transferring the primary bud strengthening cultured buds into a seedling culture medium for secondary bud strengthening and rooting culture to obtain tissue culture seedlings. The adventitious bud induction medium, proliferation medium, and seedling culture medium are all solid culture media, while the bud strengthening medium is a liquid culture medium. This invention significantly improves the propagation coefficient and shortens the seedling emergence cycle.

The invention belongs to the technical field of seedling breeding of traditional Chinese medicinal materials, and particularly relates to an efficient seedling raising method for epimedium sagittatum. The seedling raising method comprises the following steps: collecting seeds, primarily screening, collecting seeds from fruits, shelling, screening out naturally mature epimedium sagittatum seeds, and drying in the sun; treating the seeds, namely performing after-ripening treatment on the dry seeds subjected to primary screening, screening out full seeds through a water screening method, disinfecting the seeds, airing the disinfected seeds, uniformly mixing the aired seeds with river sand according to a ratio, keeping the temperature and the humidity, and storing; qualified seeds are screened out through quality detection; the qualified seeds are subjected to seedling raising, and the qualified seeds are subjected to seed dressing, sowing, seedling raising condition management and transplanting. The seedling emergence period is shortened through seed treatment and seed quality detection, the seedling emergence uniformity and the seedling emergence rate are improved, the seedling raising method is easy and convenient to operate, the seed consumption is reduced, the seedling raising cost is reduced, and large-scale application and popularization are facilitated.

This utility model relates to the field of agricultural machinery technology, and in particular to a high-ridge rotary tillage and ridging machine, including a tractor, an adjustment component fixedly installed on the right end of the tractor, a ridging and pressing machine fixedly installed on the right end of the adjustment component, a water storage tank fixedly installed on the upper end of the ridging and pressing machine, a moisture-retaining component fixedly installed inside the water storage tank, a water inlet fixedly connected to the middle of the upper end of the water storage tank, and a sealing cover provided on the upper end of the water inlet. This high-ridge rotary tillage and ridging machine, with the driving force of a hydraulic cylinder, can drive an adjustment plate to achieve stable up and down movement. The up and down movement of the adjustment plate synchronously drives the ridging and pressing machine to complete the height adjustment. The machine can precisely adjust the working height of the ridging and pressing machine according to the differentiated requirements of different crops (such as vegetables and cash crops grown on high ridges) and the actual requirements of different soil textures (such as clay soil requiring slightly higher ridges for flood prevention) during ridging operations.

The invention relates to the technical field of cultivation equipment, and discloses a bitter gourd rice planting rice seed auxiliary cultivation box which comprises a box body as a basic component of the whole device and used for assembling and bearing all processing mechanisms and subordinate lower structural parts of the processing mechanisms. And the natural simulation mechanism is arranged at the upper part of the box body and is used for simulating light, natural wind and natural rainfall environmental conditions in an external environment in a rice seed cultivation process. By adding and arranging the auxiliary stimulation mechanism, in the rice seed germination accelerating stage, the mechanism generates an alternating electromagnetic field through electrification of an electromagnetic coil, the activity of various enzymes in seeds can be effectively activated, sufficient energy and nutrition are provided for seed germination, the germination accelerating period is greatly shortened, and the germination efficiency and quality are improved; the electromagnetic field generated by the mechanism can accurately stimulate division and growth of root system cells, promote the root system to be more developed and robust, enhance the ability of the root system to absorb nutrients and moisture in soil, and enable rice seedlings to grow more robust.

The application belongs to the technical field of plant breeding, and particularly relates to a seed pretreatment method and seedling raising method for improving the breeding efficiency of Carpinus putolekii, which comprises the following steps: disinfecting Carpinus putolekii seeds, and performing temperature-variable stratification treatment on the disinfected seeds to obtain pretreated Carpinus putolekii seeds; the temperature-variable stratification treatment comprises: 23-27 DEG C warm treatment for 30 days, and 3-5 DEG C cold treatment for 60 days. The pretreatment method can significantly shorten the germination time of Carpinus putolekii, improve the germination efficiency, and provide technical support for the protection and large-scale seedling raising of the species. The results of the examples show that, by using the method provided in the application, the germination time of Carpinus putolekii seeds is reduced to 14 days, the germination rate is 93.1%, and the seedling rate is 89.7%, so the germination is rapid, and the uniformity is high.
