The invention discloses a planting method for achieving continuous high and stable almond yield under the intercropping condition. The line spaces of almond trees are determined by utilizing a fixed planting mode, a 3 meters * 7 meters planting mode suitable for intercropping is adopted, S-genotype varieties are adopted for matching, a trimming and pruning technology is adopted for high-trunk layered trees, a fruit tree moisturizing technology is adopted to meet the water demands of the almond trees and inter-planted crops, winter rapes are inter-planted in protective zones among lines to promote fertilization and insemination of the almond trees, a young fruit abscission prevention technology is adopted to decrease fruit abscission of the almond trees, and a growth regulator is applied to promote fruit setting of the almond trees, decrease fruit abscission of the almond trees and promote flower bud differentiation of the almond trees. The technical problems of the disorder fixed planting mode of the almond trees, variety matching without scientific basis, serious intercropping contradiction, severe insufficiency of bees for supplementary pollination, young fruit abscission and unreasonable growth regulator application are solved, accordingly the almond yield in the current year can be ensured, crops inter-planted among lines are not influenced, the purpose of obtaining the yield of the next year is achieved, and high and stable almond yield is achieved.

The invention discloses a machine-transplanted hybrid rice hill-reduction seedling-stabilizing large-ear culturing method. The machine-transplanted line spacing of hybrid rice is 0.30 m, and the hill spacing is adjusted to be 0.20 m to 0.25 m; the seedling grabbing area is set according to the seedling establishment percentage, and during transplanting, the number of seedlings in each hill is 3 to 5 on average so that it can be guaranteed that the number of survival seedlings in each hill is 2 to 4 after regeneration, the density is 132000 hills per hm<2> to 167000 hills per hm<2>, the average total seedling number is 240 pieces per hm<2> to 300 pieces per hm<2>; in other words, the weight of seeds per hm<2> is kept being 18 kg to 22.5 kg. According to the machine-transplanted hybrid rice hill-reduction seedling-stabilizing large-ear culturing method, the number of transplanting hills is reduced by 25.8% to 41% compared with conventional transplanting, and transplanting efficiency is greatly improved; as the number of hills is decreased without decreasing the number of seedlings, the number of seedlings in each hill is increased, the transplanting missing rate is reduced by 10 percent or above, and the number of persons for seedling supplementing is decreased by 3 to 4 per hm<2>; the machine-transplanted late-planting and late-harvesting area of multi-cropping rice fields in Sichuan is large, and rainwater after autumn is much; when the number of hills is decreased, ventilation and light transmitting become better, pest and disease damage is reduced, lodging is reduced, and large ears, more grains and high yield are achieved.

The invention provides an exploitation method of vaporizing formation water and displacing heavy oil by microwaves in situ. The exploitation method comprises the following steps: selecting an old well in the heavy oil reservoir huff and puff old well area to serve as a displacement well, and selecting a plurality of old wells adjacent to the displacement well to serve as recovery wells, wherein the recovery wells form an injection and production well group; performing fracturing and crack construction on the target oil layer in the displacement well; injecting silicon carbide particles into the cracks; arranging microwave generating equipment at the wellhead and in the interior of the displacement well; and continuously performing microwave radiation heating on the silicon carbide particles through microwaves with certain power, and further heating the oil layer, so as to enable the underground stored water generated in the huff and puff process to be vaporized in situ, displace the crude oil of which the temperature is increased and the viscosity is reduced in the well, and enable the crude oil to enter the bottoms of the recovery wells to be exploited out. The exploitation method utilizes the silicon carbide particles in the cracks to heat the oil layer, so as to vaporize the underground stored water and displace the remaining oil after huff and puff, solve the problem of loss of steam quality due to steam injection at the wellhead, reduce heat loss, improve the downhole steam quality and steam swept volume at unit mass, and improve the exploitation effect of heavy oil reservoir after huff and puff.

The invention discloses an environment-friendly oxidation-imbibition method for zero flowback of shale gas well fracturing fluid and improved recovery. In this method, oxidant is added to the fracturing fluid, and after the fracturing of the gas well, the shale and the oxidizing fracturing fluid are used to oxidize the organic matter on the fracture surface or pore surface, thereby increasing the contact area between the fracturing fluid and clay minerals, and improving the shale The imbibition ability of fracturing fluid enables the fracturing fluid in the fracture to imbibe and disperse into the pores, and the fracturing fluid in the pores dissolves organic matter and disperses into the intercrystalline pores of clay minerals, realizing zero flowback of fracturing fluid. The present invention uses oxidative fracturing fluid to improve the imbibition capacity of shale reservoirs, not only increases the effective seepage channel and gas desorption-diffusion capacity, but also avoids the environmental problems induced by fracturing fluid flowback, and returns to the shale gas well after shale gas well pressure. When the drainage is put into production, the oxidant trapped in the reservoir can continuously improve the shale gas transmission channel, which is conducive to realizing the low-cost and high-efficiency development goal of shale gas wells.
