The invention discloses a method for cultivating hardy eucalyptus forests suitable for climates at north latitude of 26-30 degrees. The method comprises the following steps: determination of the varieties of eucalyptus trees, wherein eucalyptus dunnii and meranti are selected as the varieties of eucalyptus trees; seedling raising: carrying out propagation of the seedlings by using a clonal cutting seedling raising method or a method for growing seedlings by using seedlings, when cut seedlings grow to 12-25 cm, taking the seedlings out of greenhouses for transplanting; transplanting; carryout out post-transplanting management; and preventing and controlling plant disease and insect pests. Because the climate of zones at the north latitude of 26-30 degrees are sunny, rainy and many rivers, reservoirs and ponds are located in the zones, the characteristics that eucalyptus trees are heliophilous and absorbs much water can be satisfied; in the process of planting, through artificially applying fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, a large number of organic matters, trace elements, amino acids and microbes and some active substance fertilizers, the effectiveness of nutrients can be increased; and compound fertilizers suitable for the growth of eucalyptus trees are applied to surviving seedlings every year, so that the characteristic that the eucalyptus trees absorb more fertilizer can be satisfied, therefore, eucalyptus trees artificially planted by using the method disclosed by the invention can averagely grow 4-6m in height and 3-4cm in DBH(diameter at breast height) each year, the eucalyptus trees can be cut down in batches in 4-5 years generally, and the wood yield per mu is 10-12 m<3>.

The invention relates to a corn and soybean intercropping planting method. The planting method has a corn and soybean intercropping ridge rate of 1:2. Three lines of soybeans are sown in each ridge; two lines or three lines of corns are sown in each ridge; and the soybeans or the corns on each ridge of land are planted in a dog bite mark mode. Due to the adoption of the corn and soybean intercropping planting method, a conventional mode of planting the corns in a large area is broken through, high and short stem crops are combined to be planted in one plot of land to form a height difference, and the crops have high ventilation and high wind resistance and lodging resistance. Moreover, the corns can keep out the wind, keep out the cold and shade the sunlight for the soybeans. After the planting method is adopted, the yield of the corns is same with that of the corns planted in the large area, but the yield of soybeans is increased by 60 percent per hectare, so that the limited soil resources are better utilized and the aim of increasing both yield and income of farmers is fulfilled.

The invention discloses application of a maize secretory phospholipase A2 gene ZmsPLA2-2 to changes in plant drought resistance properties. According to the application, the maize secretory phospholipase A2 gene ZmsPLA2-2 is cloned from maize and recombined into a plan expression vector in the sense or anti-sense form; the obtained fusion genes are introduced into plants according to a transgenic technology; through measurement on the drought resistance properties of the transgenic plants, the transgenic plants of which the drought resistance properties obviously improved or reduced and progenies of such transgenic plants are screened out, so that new plant germplasms with application value are created. The cDNA sequence of the maize secretory phospholipase A2 gene ZmsPLA2-2 is show as SEQ ID No.1, and the amino acid sequence encoded by the maize secretory phospholipase A2 gene ZmsPLA2-2 is shown as SEQ ID No.2. The plants of which the drought resistance properties can be changed are cultivated herbage crops such as poa annua, herbage, maize and cotton. The application of the maize secretory phospholipase A2 gene ZmsPLA2-2 has an important meaning in improvement of the crop yield under drought stress.

The invention relates to technical field of forage grass cultivation and aims at providing a high-yield method for cultivating goodyera yamiana II. According to the technical scheme adopted by the invention, the method comprises the following steps: land preparation, planting, field management, harvesting and fertilization. The goodyera yamiana II has high photosynthetic activity; the goodyera yamiana II in per mu of land can absorb 6-7 tons of carbon dioxide each year and has obvious effects on purifying air, absorbing harmful gases in the air and improving the environment; the goodyera yamiana II is planted in large areas on two sides of a highway, at the peripheries of a factories and mines and inside and outside parks, so that the air pollution degree is reduced, and the living environment of people is improved; the goodyera yamiana II is an ideal plant for preventing water and soil losses, treating stony desertification, desertization, salinization, desolate beaches and abrupt slopes; the goodyera yamiana II is soft in leaf, rich in juice and favorable in palatability, thereby being a favorable feed for various livestocks, birds and fishes.

The invention belongs to the technical field of biological bacterial fertilizer, and particularly relates to a compound microbial agent. The compound microbial agent is prepared from five soil beneficial bacteria and three synergists, wherein bacillus licheniformis (TMQD01), bacillus megatherium (TMQJ05), silicate bacterium (TMQJ01), rhodopseudomonas palustris (TMQZ08) and lactobacillus cased (TMQR01) are mixed according to the effective viable counts being (0.8-1):(0.8-1):(2.5-3):(1.0-1.2):4, and it is ensured that the viable count is not smaller than 3 billion / ml; organic acid, water solubleamino acid, gamma-polyglutamic acid and other synergists, solid phosphorus and potassium in soil are dissolved, available phosphorus and potassium in soil are increased, the purpose of dissolving phosphorus and potassium is achieved, the photosynthetic effect rate is increased, plant fructification is promoted, crop disease resistance is improved, and the effect of reducing agricultural capital input is achieved.

The invention discloses a stereoscopic cultivation method of Trichosanthes kirilowii Maxim and Volvariella volvacea. In the method, a shady field formed by Trichosanthes kirilowii Maxim sheds is fully utilized for planting Volvariella volvacea so as to increase planting earnings; besides, by planting Volvariella volvacea, soil organic matter for Trichosanthes kirilowii Maxim can be increased, the soil environment can be effectively improved, and soil diseases of Trichosanthes kirilowii Maxim can be reduced. By means of the cultivation mode, the land utilization rate can be effectively increased, and the economic benefit can be increased. The stereoscopic cultivation method of Trichosanthes kirilowii Maxim and Volvariella volvacea includes the following steps that in April, 2-3-year Trichosanthes kirilowii Maxim root tubers are selected, cut into segments and then planted in a field, after seedlings emerge, the sheds are built according to Trichosanthes kirilowii Maxim planting gaps, the Trichosanthes kirilowii Maxim seedlings are led onto the sheds, and meanwhile Trichosanthes kirilowii Maxim pruning is carried out; in the middle of June, making of a Volvaria volvacea strain is started, and meanwhile fermentation treatment of culture material is carried out; 15 days later, the strain is sown under the Trichosanthes kirilowii Maxim sheds, earthing-up is started after 2 / 3 of the fermented material is grown with hyphae, and then normal fruiting management and harvesting are carried out; Trichosanthes kirilowii Maxim is harvested in November.
