According to the fertilizer application method, the original independent and separated cultivation management mode of tobacco crops and rice crops is changed, the tobacco leaf quality control is moved forward to the rice season, and the chlorine content of succeeding tobacco leaves is reduced and the quality of the succeeding tobacco leaves is improved by applying the fertilizer to the rice.

An anchor that can be opened by water operation includes an anchor rod, an anchor claw seat, a movable anchor claw and a locking component. In addition to the conventional anchor rope (chain), there is also an action rope (chain), and the anchor claw is connected to the anchor claw seat with a rotating shaft. Pulling the action rope (chain) can cause the locking component to move, causing the locking state between the locking component and the anchor claw to be released, the anchor claw to open, and lose its grip. The anchor rope (chain) can then be recovered from the boat and the anchor can be retrieved. The present invention makes anchoring easier. If the anchor weight does not exceed human capacity, manual anchoring can be achieved. When applied to the fields of fishery production, water sightseeing, outdoor fishing, etc., there is a wider range of options for anchorages, it can be more convenient to transfer sites, realize multi-point operations, greatly expand the use scenarios, facilitate people's production and life and recreational fishing and other activities, and also provide more convenience for outdoor climbing activities.
