Method for breeding industrial hemp in greenhouse

The invention discloses a method for breeding industrial hemp in a greenhouse and belongs to the field of crop planting. Due to the breeding operation needs of hemp, increasing-generation reproduction is performed in the greenhouse, and crossbreeding is performed. Preparation of greenhouse breeding is performed after hemp seed harvesting for seeding in autumn. The invention aims to provide a method for breeding the industrial hemp in the greenhouse. The method disclosed by the invention comprises the steps of soil loosening before seeding, disinfecting and fertilizing, soil ridging, seeding of industrial hemp, performing field management on seedlings, performing management in a growth period of the industrial hemp, pollinating the industrial hemp and harvesting the industrial hemp seeds. According to the method disclosed by the invention, the defects in an isolation method in the prior art are overcome, the land space utilization ratio of greenhouse breeding is increased, different hybridized combinations are completed in the same place, the isolation effect is excellent, the isolated heterogonous plant rate is controlled to be 1-5%, the heterogonous plant hybrid rate is reduced by 10-14% due to mixing of varieties, and the labor intensity of scientific research personnel is reduced.

Preparation method of ultramicro spirulina powder as well as preparation and application thereof

The invention discloses a preparation process of ultramicro spirulina powder. The preparation process of the ultramicro spirulina powder comprises the following two steps: (1) directly superfine grinding the spirulina; and (2) uniformly mixing the spirulina water extract and the extracted spirulina residue product to obtain the spirulina powder. The average grain size of the spirulina powder is 200-800 nm. The prescription and the preparation process of the tablet, the capsule and the soft capsule of the ultramicro spirulina powder and the common spirulina powder (less than 100 meshes) are created and researched based on the ultramicro spirulina powder. The additive amount of the auxiliary materials is greatly reduced; by adopting the new preparation molding process, the problems of unreasonable prescription of the current spirulina product, many auxiliary materials, multiple varieties, low purity, tedious production process and low product quality can be solved; and the industrial production speed can be quickened and the production efficiency can be increased. The prepared product is detected. The function test proves that the ultramicro spirulina powder and the common spirulina powder have the radiation-proof effect and liver-protective effect.

Omnidirectional dual circularly polarized antenna with same-side feeding

The invention provides an omnidirectional dual circularly polarized antenna with same-side feeding. The antenna comprises a radiation structure, a similar coaxial impedance matching structure, and a radio frequency excitation conversion T-shaped connecting structure, the similar coaxial impedance matching structure is divided into an upper similar coaxial impedance matching structure and a lower similar coaxial impedance matching structure, the upper end and the lower end of the radiation structure are respectively connected with the lower end of the upper similar coaxial impedance matching structure and the upper end of the lower similar coaxial impedance matching structure, the upper end of the upper similar coaxial impedance matching structure is sealed by a metal disc plate, the lower end of the lower similar coaxial impedance matching structure is connected with the radio frequency excitation conversion T-shaped connecting structure, and an interface of the radio frequency excitation conversion T-shaped connecting structure can directly perform radio frequency excitation by employing an SMA joint feed line. According to the antenna, the omnidirectional performance and the axial ratio performance are good, a certain working bandwidth of -10dB bandwidth 600M (5.2GHz-5.8GHz) is achieved, and in-band gain is greater than 5.2dB and can reach 6.7dB to the maximum.

High speed data cable

ActiveCN103208335AGood isolationImprove the problem of crosstalk between groupsCables with twisted pairs/quadsPhysicsElectrical conductor
The invention belongs to the technical field of wire cables, and particularly relates to a high speed data cable. The high speed data cable comprises four groups of insulated wire pairs, and a sheath layer coating all the insulated wire pairs. The high speed data cable is characterized in that each group of insulated wire pairs comprises two mutually twisted insulated wire cores and a coating layer coating the two insulated wire cores and allowing positions of the two insulated wire cores to be fixed; each insulated wire core consists of a conductor in an inner layer, a shielding tape coated outside the conductor, and an insulating layer coated outside the shielding tape; the shielding tapes consist of bonding inner layers, shielding layers and bonding outer layers which are bonded together sequentially; the thicknesses of the bonding inner layers are greater than those of the bonding outer layers; the bonding inner layers are in contact with the conductors; the bonding inner layers and the bonding outer layers are made of the same material; and the insulating layers and the bonding outer layers are made of the same material. The high speed data cable has the main beneficial effects that the high speed data cable is simple in structure, convenient to manufacture, high in finished product yield, stable in cable structure and low in crosstalk, and is suitable for high-frequency and high-speed transmission.
