The invention relates to a bletilla striata seed direct-seeding seedling raising method. Common seedling raising substrate, pesticides and fertilizer sold on the market are mixed, then the mixture is laid on field ridges, the laying thickness is 1-3 cm, the complex steps of producing complex substrate materials and blending substrate are omitted, meanwhile, the consumption of the substrate is greatly decreased, and the cost is saved; bletilla striata seeds, potato starch, rooting powder and an MS dry powder culture medium are mixed in a certain ratio, a seed mixture is obtained, the bletilla striata seeds are incompletely developed in nature and have no endosperms, the potatoes starch, the MS dry powder culture medium and the bletilla striata seeds are mixed to provide nutritional substances necessary for germination of the bletilla striata seeds and are equivalent to endosperms of bletilla striata, the rooting powder serves as plant exogenous hormone to stimulate rooting and germination of the bletilla striata seeds, and the germination rate of the bletilla striata seeds is increased. The method is simple to operate, raw materials are simple and available, the cost is low, the growth cycle is short, and the seed germination rate is high.

A human body detector includes a microwave generator (10), a microwave receiver (20), a mixing detector (30) and a signal processor (40), wherein the microwave generator (10) is configured to A probemicrowave propagating in a sounding space is emitted, wherein the microwave receiver (20) is configured to receive a corresponding echo of the probe microwave, wherein the mixing detector (30) is coupled to the microwave generator (10) and the microwave receiver ( 20), and is configured to perform mixing detection on the probe microwave and the corresponding echo to output a corresponding primarydetection wave signal, wherein the signal processor (40) is connected to the mixing detector (30) and is set In order to be able to select and amplify the primary detection wave signal outputted by the mixing detector (30) to output a secondary detection wave signal of a specific fluctuation frequency range, the human body detector responds to the action of the action frequency in a specific frequency range. It is amplified so that the presence of the human body can be judged in response to the action of a specific frequency range.

The invention provides a method for selecting a cooperative set in the cooperative multipoint communication. The method comprises the following steps of configuring a nonzero power CSI-RS (Channel State Indication Reference Signal) pattern to each transmission point in a measuring set, configuring REs (Resource Elements) of other transmission points into a mute state at a position corresponding to a CSI-RS of each transmission point, and configuring a small number of PDSCH REs (Physical Downlink Shared Channel Resource Elements) of each transmission point at the same position into a mute state; according to acquired reference signal receiving power of the CSI-RS of each transmission point and the sum of interference and noise outside the measuring set, which are inquired from the mute PDSCH REs, calculating approximate single point CQIs (Channel Quality Indicator) of each transmission point by cooperative UE (User Equipment); and finally, on the basis of the approximate single point CQIs of each transmission point, determining which points in the measuring set are selected into the cooperative set. The method not only solves the problem of deficiency of accuracy, which is caused by the case of not considering the CQIs and interference, but also solves the problem of excessively high complexity caused by the case of carrying out channel estimation and calculating the single point CQIs at the UE end, so that good balance is obtained on the aspects of accuracy and complexity and a CoMP (Cooperative MultiPoint) system is simpler and also has more reliable performance.
