The invention provides a harvest management method for asparagus in southern Anhui region. The method comprises the following steps of (1) keeping the temperature at about 25DEG C and cutting away stems and not leaving buds before the first month of the lunar year under the greenhouse condition in the first year; (2) harvesting with hands in February and March of the solar calendar, allowing plant dormancy and applying a fertilizer in March-May of the solar calendar, and harvesting on August 15 of the lunar year in the second year; (3) harvesting every other 3-4 months without dormancy in the harvest peak in the third and fourth year; (4) harvesting with hands in February and March of solar calendar each year, allowing plant dormancy and applying a fertilizer in March-May of the solar calendar, and harvesting on August 15 of the lunar year in the fifth-fifteenth year. By adopting the planting method, the yield is higher, diseases are prevented, the management is easier, and the harvest time is prolonged, so the planting method has the advantages that weeds are not easy to breed, the asparagus difficultly has diseases, the land is utilized more reasonably, the cost is reduced, the economic life of the asparagus is longer, and the asparagus can be harvested for about 15 years and is better in mouthfeel.

The invention provides a planting method capable of increasing nicotine content in cut tobacco and the quality of the cut tobacco and belongs to the technical field of cut tobacco production. The method includes the steps of firstly, removing 2-3 tobacco leaves near the ground 30-45 days after flue-cured tobacco transplanting; secondly, removing tobacco leaves away from the ground and growth points to keep 17-18 tobacco leaves 3-8 days after the removing of the tobacco leaves close to the ground to obtain flue-cured tobacco seedlings after topping; thirdly, when the top tobacco leaves of the flue-cured tobacco seedlings after topping are parallel to the top, removing imperfect tobacco leaves to keep 13-14 tobacco leaves to obtain finely trimmed flue-cured tobacco seedlings; fourthly, harvesting the tobacco leaves 20-30 days after the maturity of the finely trimmed flue-cured tobacco seedlings. By the method, the nicotine content in cut tobacco can be increased while the high-quality taste of the cut tobacco can be guaranteed, the contradiction between 'high nicotine content' and 'high quality' is solved, and both 'high nicotine content' and 'high quality' can be achieved.

The invention provides a tree-mounted desiccated grape cultivation method. The method belongs to the technical field of delayed harvesting of wine grapes. The method mainly comprises the technical operating links of prescription fertilization, load control, berry protection and the like. In the method, wine grape varieties are used as objects; the element ratios of various fertilizers, damage by diseases and insects and fruit cluster bagging are controlled by controlling the number of young sprouts and the amount of fruit clusters of each young sprout on unit treillage surface, soil fertilization application and foliage application, so that the berry is protected; the grape harvesting is delayed; and the grapes can still be kept for over 100 days on trees after being matured and even reach an icing state, so that the grape berry is naturally desiccated and dehydrated and has sugar content of over 300g / L. The desiccated grapes produced by adopting the method not only have high sugar content, but also have various concentrated flavor compound ingredients. High-grade sweet wine or ice wine with more full-bodied and fragrant flavor and more rich nutritions can be produced by using thedesiccated grapes as raw materials.

The invention relates to a double-bed two-stage panax notoginseng harvester, and belongs to the technical field of traditional Chinese herbal medicament machines.
