44results about How to "Improve matching effect" patented technology

A method for matching weight iteration nodes between weighting networks includes the steps: firstly, selecting matched node pairs; secondly, calculating similarity by respectively connecting two unmatched nodes from different networks with k matched node pairs l=1, 2, ..., recording the weight of a connecting edge between vi1 and vl1 as wl1, recording the weight of a connecting edge between vj2 and vl2 as wl2 and defining the similarity of the nodes between the weighting networks as (4); thirdly, matching the nodes by selecting a pair of unmatched nodes with the highest similarity and belonging to different networks as a current matching node pair in each turn of iteration, considering the pair of unmatched nodes as a newly revealed matched node pair, turning to the second step and recalculating the similarity according to the formula (4); and fourthly, finishing matching until all the nodes in one target network are matched. By the method, matching effect and matching precision are improved.

The invention relates to a rice dry-planting seedling disc as well as a seedling raising method and application thereof, belonging to the technical field of agricultural machinery equipment. The rice dry-planting seedling disc comprises a disc body, bowl bodies and support bodies, wherein the bowl bodies are inverse cone bodies and are located in the disc body; at least three grooves are formed in the disc body, and the support bodies are located in the grooves; the support bodies are used for supporting the seedling disc so as to conveniently place seedlings on a rice dry-planting machine in piles. By raising the seedlings by virtue of the seedling disc, soil at the roots of the raised seedlings is moderate in dryness and humidity, is dry and comfortable, is agglomerated and is not easily scattered during mechanical dry planting, so that the operations of seedling separation, seedling transportation and mechanical dry planting are easily realized. The seedling disc is applied to the specific rice dry-planting machine and is excellent in energy conservation; compared with a traditional rice transplanter which is high in mechanical energy consumption while walking in an irrigated land, the rice dry-planting machine which is used for planting the seedlings on a dry farmland has the advantages that the more energy is saved, and the speed is relatively high; the operation time can be conveniently controlled, and the seedling transplanting time can be shortened; compared with a seedling throwing manner, a mechanical seedling transplanting manner and a manual seedling transplanting manner, the seedling transplanting time can be shortened.

The present invention relates to a mechanized dry transplanting method for rice, and belongs to the technical field of cultivation for agricultural crops. The method comprises the following steps: (1) seedling raising: adopting a plug for seedling raising, wherein the plug comprises a plate body and a bowl body, the bowl body is an inverted circular truncated cone which is located in the plate body, seedling culturing soil and rice seeds are inserted into the bowl body, and the seedling age of the seedling is 20-30 days; (2) soil preparation: after wheat or rapeseed is harvested, applying a rice basal fertilizer, carrying out rotary tillage on the land and preparing the furrow ridge; (3) dry transplanting: adopting a dry planting machine for rice provided by the present invention for transplanting, wherein the dry planting machine for rice comprises a driving apparatus, a seedling placing platform, a seedling separating track, a press wheel and at least one soil cover mechanism, as the rice dry planting machine constantly marches forward, the seedling constantly falls into a ravine and the ravine is filled by soil; and (4) irrigation: in 2 to 3 hours after the rice seedling is dry transplanted, irrigating water to prevent the seedling from being sunburn. According to the method provided by the present invention, mechanized operation for dry transplant for rice can be realized, so that the method is applicable to large-scale production application, low in cost and highly effective.

A kind of sour plum black tea beverage, comprises compound type sour plum black tea essence, purified water and auxiliary material, described sour plum black tea essence is made up of sour plum essence and black tea essence, and the mass ratio of described sour plum essence and black tea essence is 3:2~1:1; in the sour plum black tea beverage, the mass percentage concentration of the sour plum black tea essence is 0.05%-0.1%, and the mass percentage concentration of the auxiliary materials is 6~6.5%; The balance is purified water. The present invention also provides the preparation method of the above-mentioned sour plum black tea beverage, which is formed by compounding sour plum essence and black tea essence according to a certain ratio, adding pure water and appropriate auxiliary materials in sequence, and then pasteurized filling. In the present invention, the compound essence of sour plum black tea is compatible with natural extracts, and is applied to the beverage formula as a flavor component, so that the flavor substance can provide the aroma effect of fresh sour plum and Guangdong Yingde black tea in the beverage, and make up for the effect of concentrated fruit juice and black tea on the beverage formula. Characteristic aroma missing after thermal processing.
