The invention discloses a eucalypt tissue culture medium comprising a subculture medium and a rooting medium. The culture medium has the advantages that subculture plantlets of eucalypt materials have high proliferation rate and high regeneration rate, grow well and evenly and are strong, have dark green leaves and few vitrified shoots and the like; roots can directly develop without going through a plantlet-promoting stage; and the rooted plantlets have high rooting rate and high transplanting survival rate as well as strongly-developed root systems, and are fast in rooting and good in survival rate of transplanting.

The present invention relates to a seedling substrate for solanaceous vegetables and a producing method therefor. The seedling substrate comprises a mixture obtained by mixing a main material, vermiculite and perlite in a volume ratio of 3-4 : 0.6-0.7 : 0.3-0.4, and is obtained by adding 10 g to 15 g of paclobutrazol and 1.5 kg to 2 kg of 0.4 mol / L to 0.5 mol / L dilute sulfuric acid solution per cubic meter of mixture, and fully mixing same until uniform. Said main material is obtained by adjusting a cow bedding removed material to a carbon / nitrogen ratio of 25-30:1, a pH value of 6.5-7.0, and a water content of 60%-65%, then introducing EM fermentation bacteria, stacking, covering a film, and performing high temperature aerobic fermentation and air drying. By using the substrate to grow seedlings, the root systems are well developed and will not grow wildly, the seedlings are strong, damping-off and root rot are significantly reduced, and the damage caused by aphids are reduced; virus diseases during the seedling being planted in the field are reduced, and the yield is increased by 14% to 19%.

The invention discloses a tissue culture rapid propagation method of populus tremula multiplied by P. tremuloides, which comprises the following steps: (1) inoculating an explant of the populus tremula multiplied by P. tremuloides on a start culture medium for culture after sterilization and obtaining an aseptic tube seedling; (2) cutting the tube seedling obtained in the step (1) into sections, and inserting into a differentiation culture medium for culture; (3) inserting the seedling sections obtained in the step (2) into a rooting culture medium for carrying out rooting culture; (4) transferring the seedling sections after rooting into the rooting culture medium for successive transfer culture; and (5) finally carrying out acclimatization and transplantation. The tissue culture rapid propagation method of populus tremula multiplied by P. tremuloides has the advantages of rapid seedling growth rate, high survival rate, robust seedling, tender green leaf color, difficult vitrification, low production cost, industrialized production and the like.

The present invention relates to a new-type pests-killing and disease-preventing seed-dressing agent. Its composition includes fludioxonil, isofenphos-methyl raw medicine and adjuvant. Its pH value is 6.5-7, in said seed-dressing agent the plant growth regulator sodium nitriphenolate also can be added. Said invention is application to wheat, corn, cotton and peanut. Besides, said invention also provides its concrete application method.

The invention discloses a method for planting sweet corn with three harvests a year. The method is to plant sweet corn for three seasons in a year and rotate green manure once a year. 50 days and 65 days after corn transplanting, plant protection drones were used to spray sugar-increasing fertilizers to increase the sugar content of corn. The method of the invention not only rationally utilizes the land, improves the output rate of the land, but also improves the soil through crop rotation, alleviates the continuous cropping obstacle of the soil, and realizes the farming mode combining land use and land cultivation.

The invention discloses a soilless culture seedling-growing method for cress. The method comprises the steps as follows: firstly, a seedling-growing disk and a seedling-growing matrix are prepared, the seedling-growing matrix is formed by tiling a plurality of small sponge pieces, and a cross through hole is formed in the middle of each small sponge piece; then the seedling-growing matrix is tiled in the seedling-growing disk; cress seeds are uniformly spread on the seedling-growing matrix, 8-12 cress seeds are arranged on the surface of each small sponge piece, and the seedling-growing disk where the cress seeds are spread is placed in a greenhouse with sufficient sunlight; watering and fertilizing are performed at fixed time, and planting can be performed when strong cress seedlings are cultured initially. According to the seedling-growing method, the yield of the cress seedlings is high, the quality is good, sanitation and hygiene are realized, the method is not limited to seasons, the harvest is convenient, and the cress can be sold in the market yearly and has larger market prospects and economic valves.

The invention discloses rice seedling raising seed covering soil. A raw material formula of the seed covering soil comprises the following components in parts by volume: 3-5 parts of thoroughly decomposed agaricus bisporus and grass soil mixture, 2-3 parts of edible fungi leftovers, 1-2 parts of pond sludge, frozen soil or humus and 2-3 parts of rice chaff ash; besides, a proper amount of acidified soil and disinfectant and a soil conditioner with weight accounting for 0.1-0.3% of the total weight are added. The organic materials in the raw materials are thoroughly decomposed by adopting a high-temperature decomposition agent through composting fermentation and are mixed with other materials uniformly after being dried and ground, thus obtaining the rice seedling raising seed covering soil. The physicochemical indexes of the seed covering soil are as follows: the water content is not more than 50%, the organic matter is not less than 30%, the total porosity is 60-75%, the volume weight is 0.35-0.6g / ml, the total nutrient content is 1.5-2%, the pH value is 5.5-7, the EC value is not more than 3mS / cm and the granularity is not more than 4.5mm. By taking the mushroom leftovers as the main raw materials and fermenting the mushroom leftovers by adopting effective microorganisms, the seed covering soil has excellent effects, is very suitable for rice seedling raising, can promote rice seedlings to grow robustly and can be popularized and applied across the country.
