The present invention relates to a method for modulating plant processes said method being characterized in that a plant is fed with an eco-friendly, plant- and/or algae-derived, biostimulant composition comprising exogenous small RNA molecules. In particular, the method of the invention can be used for modulating physiological or pathological plant processes, such plant growth, plant productivity, fruit quality, quality of produce, plant yield, plant response to abiotic stress and plant resistance to diseases or to infections.

The invention discloses a cutting and grafting integrated fast reproduction method for camellias. The method is characterized in that the cutting is conducted on Camellia oleifera branches with stems greater than 3.0 cm in diameter for years, and there are more nutritive materials in large cuttings to provide a certain amount of nutrients for rooting at the base of the cuttings and scion sprouting, thereby promoting rapid forming; and meanwhile, the grafting is conducted on the top end of the cuttings with the scion of a targeted camellia variety; the camellia variety scion retains 2-3 pieces of whole-leaves which are used as functional leaves for photosynthesis; the nutrients produced by the photosynthesis further provide the needed nutrients for growth. The cutting and grafting integrated fast reproduction method completely overcomes the shortcomings of other reproduction methods, and is a novel and fast reproduction method with the advantages of being innovative, fast in forming, ahead in flowering, good in quality, low in production cost, high in yield, quick to take effect and good in seedling quality.

The invention relates to a process for storing cut flowers of peony and Chinese herbaceous peony for a long time. The process comprises the following steps of: collecting the peony and the Chinese herbaceous peony in the bud period; eliminating soil; decreasing the shell temperatures of the peony and the Chinese herbaceous peony to 15-20 DEG C; carrying out water cutting at the part which is 10-20 mm away from the basal parts at the pedicel lower ends of the peony and the Chinese herbaceous peony; placing flower stalk ends of the peony and the Chinese herbaceous peony in protective agent for 2-3 h; then, taking out; decreasing the temperatures of the peony and the Chinese herbaceous peony to 5-8 DEG C; placing the peony and the Chinese herbaceous peony in a preservation box; placing the preservation box in a storage box; storing the peony and the Chinese herbaceous peony at minus 2 to minus 8 DEG C at the relative humidity of 85-95%; in the process of inserting the peony and the Chinese herbaceous peony in a bottle, taking out the storage box with the cut flowers of the peony and the Chinese herbaceous peony in the bud period in a sealed manner; recovering the temperatures of the cut flowers of the peony and the Chinese herbaceous peony for three times so that the shell temperatures of the cut flowers of the peony and the Chinese herbaceous peony are up to 15-20 DEG C; and opening the storage box and the preservation box to insert the cut flowers of the peony and the Chinese herbaceous peony in the bottle. According to the process for storing the cut flowers of the peony and the Chinese herbaceous peony disclosed by the invention, the problems of short storage period of the peony and the Chinese herbaceous peony, complex storage process and the like are solved; and thestorage time of the peony and the Chinese herbaceous peony in the cut flower period can be prolonged.

The invention relates to a pesticide insecticidal composition containing spirotetramat and pyridaphenthion, and the insecticidal composition is highly effective for controlling harmful organisms. The pesticide insecticidal composition containing the spirotetramat and the pyridaphenthion contains the active ingredients, namely the spirotetramat and the pyridaphenthion, wherein the weight ratio of the spirotetramat to the pyridaphenthion is 50: 1-1: 50. The active compound combination disclosed by the invention has special systemic property, namely by using the insecticidal composition disclosed by the invention to perform treatment on seeds, the seeds can be protected, and plants obtained after germination can be further protected from being damaged by pests. Therefore, the immediate treatment of crops during seeding or slightly after seeding can be avoided; compared with various independent active compounds, the active compound combination disclosed by the invention has synergistically increased insecticidal activity; the insecticidal activity exceeds the sum of activities of two active compounds during respective application, so that the optimization of the quantity of the used active compounds becomes possible.

The invention discloses a cultivation method of Richard delicious apple trees formed through reproduction and bud mutation of honglu apple trees and superior apple trees. The cultivation method comprises the steps of 1) planting, 2) preparation of powder, 3) pollination, 4) sifting, 5) grafting and 6) management and determination. By means of the method, apple nursery stocks with high quality canbe obtained through cultivation, the Richard delicious apple trees are high in flowering rate and have strong disease resistance, there is no yield distinction in biennial bearing of fruits, the yieldis high, and borne fruits are large, high in sweetness, high in juice yield, and uniform in color and have red bright fruit peel.

The invention provides a special fertilizer for potted cottonrose hibiscus, which comprises the following components in percentage by mass: 31.2-99.7 wt% of an organic fertilizer, 0.1 to 66.1 wt% of apotassium-containing mineral and 0.2-16.5 wt% of a chemical fertilizer mixture; wherein the chemical fertilizer mixture comprises a nitrogen fertilizer, a potassium fertilizer, a phosphate fertilizerand a controlled-release nitrogen fertilizer. The invention also provides an application method of the special fertilizer. Organic matters, the potassium-containing mineral and soil are fully mixed to prepare mixed soil, the mixed soil provides sufficient nutrients for cottonrose hibiscus, and then the chemical fertilizer mixture is applied to the positions 3-5 cm away from the root of the cottonrose hibiscus and 5-10 cm away from the ground surface, so that long-term nutrition is provided for the long-term fertilizer efficiency of the cottonrose hibiscus by adopting the special fertilizer and the application method, soil hardening can be effectively reduced, nutrient requirements of growth of the cottonrose hibiscus can be met, and the flowering phase quality of the cottonrose hibiscus can be improved.

The invention discloses a cost-saving high-efficiency northern facility cultivation method of butterfly orchids. According to the method, after tissue culture bottles are sealed and germs are isolated, rooting cultivation of butterfly orchid tissue culture seedlings is carried out in a greenhouse, so that space in a tissue culture room is saved, and extra seedling hardening is not needed. Root systems does not need to be washed when the tissue culture seedlings are taken out of the bottles, transplanting is carried out directly, immediate watering is not needed after the field planting, and watering can be carried out after a matrix is dried, so that the emergence step of the butterfly orchid tissue culture seedlings is simplified, and the transplanting efficiency of the butterfly orchid seedlings is remarkably improved. When a 3.5-cun cup is replaced, peat is used, so that the cost is reduced, butterfly orchids better adapt to northern climate characteristics, and the flowering quality is improved.

The invention belongs to the technical field of fruit tree planting, in particular to a method for high-yield cultivation of litchis. The method for the high-yield cultivation of the litchis is characterized in that rational fertilization is carried out in a cultivation process of the litchis, and the principles of frequently fertilizing and thinly fertilizing are followed; a whole year mainly includes three fertilization periods, the first time of fertilization is carried out before flowering, the second time of fertilization is carried out within the 10th day to the 15th day ever since litchi flowers wither, and the third time of fertilization is carried out in the period of 7 to 20 days before fruit harvesting. Compared with the traditional fertilizing method, the method provided by the invention can improve the yield and quality of the litchis.
