Energy efficient wireless sensor network routing method

The invention discloses a routing method for the wireless sensor network with efficient energy, which is suitable for the layered sensor network structure. The routing method is composed of initialization, cluster building, adjacent clusters routing and routing maintenance, wherein, an initialization process of the protocol makes a Sink node obtain a topology and network average energy of the sensor network, and each node obtains hop counts from the node to the Sink node; in the stage of the cluster building, a repeated division method is used to divide sensor network clusters, the divided clusters are even, and a leader cluster node is undertaken by nodes with higher residual energy; the adjacent clusters routing uses an ant colony algorithm to determine the probability of using a link to send information according to the link pheromone concentration, and the link pheromone concentration is increased with the information transmission on the link and is reduced with the time going; and the routing maintenance stage is responsible for updating link pheromone concentration, and makes the nodes inside the cluster with higher residual energy undertake the leader cluster in turn. The routing method can reduce the consumption of the network total energy, can balance the consumption of the node energy and can prolong the network life cycle.

Teak low-chipper sprout-promotion rapid-propagation seed-growing method

The invention discloses a teak low-chipper sprout-promotion rapid-propagation seed-growing method. Seeds are soaked by lime water and gibberellin and then sowed, then seedlings are transplanted into a first nutrition substance container to cultivate mother seedlings to a stage when leaves are mutually overlapped, then the seedlings are graded and arranged according to certain planting space, when ground diameter of the mother seedlings is 0.4-0.8cm, the mother seedlings are planted into a plastic pot with a bottom support to be bred, wherein the mother seedlings are not separated from container cups, and second nutrition substance is arranged in the plastic pot. After 10-15 days, the mother seedlings are cut at a position where base parts of the mother seedling are close to the ground to promote sprouting, collecting cuttings and arranging the cuttings in a container cup provided with third nutrition substances in cottage mode, growing seedlings on an elevated seedling bed in a plastic greenhouse, controlling air temperature and relative humidity of a cottage bed by utilizing a greenhouse temperature and moisture adjuster, and thus obtaining teak container cottage seedlings. By means of the teak low-chipper sprout-promotion rapid-propagation seed-growing method, cottage branches are short, interval time of cutting collection is shortened, breeding efficiency is improved, field condition requirements of nursery gardens are not strict, management is convenient, cutting quality is easy to control, cottage survive rate is high, and economic benefit is good.

Method for improving tree seedling survival rate

The invention discloses a method for improving tree seedling survival rate, which comprises the steps of: 1) excavating planting holes: excavating the planting holes according to the size of tree seedling soil balls, laying pebbles at the bottoms of the planting holes, laying geotextiles, laying coarse sand and filling yellow soil in the planting holes; 2) planting tree seedlings; 3) supporting and binding the tree seedlings; 4) irrigating the tree seedlings: spray freshwater to the branches and the trunks of the tree seedlings before a.m. 10 o'clock of every day, spraying mixed solution of urea, potassium dihydrogen phosphate and water to the branches and the trunks of the tree seedlings after p.m. 5 o'clock of every day, continuously irrigating for 1-2 months and finally conducting normal irrigation to the tree seedlings.
