The invention discloses an adult-walnut-tree total-crown grafting method which solves the problems that the grafting cross section of a traditional adult-tree stump is large, the survival rate is low, and the crown recovery speed is low. The adult-walnut-tree total-crown grafting method includes the technical steps of rootstock selecting and processing, scion selecting and processing, grafting time determining, rootstock and scion cutting, grafting, after-grafting managing and the like. The adult-walnut-tree total-crown grafting method is high in grafting survival rate, negative effects on a tree body can be reduced, the tree vigor can be prevented from being early aged, the crown recovery speed is high, and the yield of a walnut low-yield forest is rapidly improved.

The invention discloses a method for rapidly cultivating rosa chinensis minima potted flowers by pinching for one time. The method comprises the steps of direct cutting in flowerpots and directional seedling growing for one time and pinching and trimming for one time in the seedling stage. Compared with a traditional multi-step potted flower cultivation method that seedlings are first cultivated and then potted, the production steps of seedling potting and transplanting, and combining and molding are reduced, damage and investment which are caused by seedling potting and transplanting are prevented, survival rates of the seedlings are increased, rooting and sprouting are ordered and consistent, and production cost is reduced. The number of flower branches and extension directions of foliage leaves can be directionally cultivated by the technologies of directional cutting and pinching and trimming for one time, the sprouting time of plant buds and consistency of flower branch growth are ensured, the potted flowers are promoted to the molded rapidly and fully, ornamental characteristics are largely improved, insect diseases are prevented, the ratio of high-quality potted flowers is significantly improved, the production cycle is as short as 60-85 days.

The invention discloses a system capable of real-time treatment of toxic gas in sewage pipes, comprising several vertical pipes and horizontal sewage pipes, the several vertical pipes are all connected to the horizontal sewage pipes, and the inner wall of the horizontal sewage pipes is provided with an ultrasonic flowmeter , the inner wall of the horizontal sewage pipeline is provided with a wireless sensor group, and the vertical pipeline is provided with a sewage gas treatment device. The sewage gas treatment device includes a feed pipe, one end of the feed pipe is fixed on the inner wall of the vertical pipe, and the other end of the feed pipe is provided with a first casing, the first casing is far away from the One end of the feeding pipeline is provided with a storage bin group, and the storage bin group is composed of several storage bins. Beneficial effects: it can effectively prevent the harmful gas in the sewage pipe network from accumulating to a dangerous concentration, reduce the burden of the central treatment of sewage, and greatly reduce the probability that the toxic gas will harm the human body.

The invention discloses thiacloprid-containing ointment for preventing and treating forest pest poplar longhorned beetles, and belongs to the fields of pesticides and preparations thereof. The thiacloprid-containing ointment is prepared by blending 0.1-50% of thiacloprid, 0.1-50% of quintiofos and the balance of additives in percentage by total weight of the ointment, wherein the additives comprise 0.1-80.0% of solvent, 0.1-80.0% of adhesive and 0.1-80.0% of packing in percentage by total weight of the ointment. The thiacloprid-containing ointment is applied to stripped barks, has good adhesive force and persistent effect and is simple and convenient to apply; the utilization rate of the ointment is increased; the environmental pollution is reduced; the ointment can pass through plant epidermis and enter the plants; and the thiacloprid-containing ointment has certain contact action and is capable of preventing the pests from creeping up and down on tree trunks, thus the damage on the plants can also be greatly reduced.

The invention discloses a sex attractant for Spodoptera moth and its application, which belong to the technical field of insect sex pheromone preparation. The sex attractant of the present invention comprises cis-11-hexadecene-1-alcohol and trans-7-dodecene acetate, and the masses of the two are 850 μg and 150 μg respectively, which is the optimal ratio. The trapping effect is the best when the lure core of the moth-lacking attractant is placed in a box-type trap for trapping. The sex moth attractant provided by the invention can effectively lure male moth moths, reduce the risk of harm to offspring, and has a strong trapping ability; it has strong species specificity, does not harm other beneficial species, and is environmentally friendly; it has good stability and a long-lasting effect Long, it can trap and kill noctuid moths for a long time, and control the population below the harmful level. The sex attractant of the present invention can be applied to the insect situation monitoring, mass trapping and interfering mating of Spodoptera moth, and is of great significance for green prevention and control of Spodoptera moth.

The invention relates to a preparation method of a fertilizer, in particular to an organic fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. The organic fertilizer comprises the following components in parts by weight: 5-20 parts of bone meal, 2-8 parts of hoof and horn meal, 30-50 parts of feces, 12-18 parts of shale, 8-12 parts of plant ash, 15-25 parts of humic acid, 0.7-0.9 parts of bacteria and 0.05-0.2 parts of sugar. The organic fertilizer can effectively improve the appearance of vegetables and fruits and increase the amino acid content; the using amount of each pesticide is reduced, and harmful chemical substances such as heavy metal, and pesticide residues are effectively reduced, so that a nuisanceless requirement is met and the preparation method is an agricultural production technology which is quite worth of popularization.
