This invention discloses a rapeseed seed coating agent and a method for mechanized transplanting using dual-purpose rice-oilseed trays, relating to the field of agricultural seedling technology. The rapeseed seed coating agent comprises the following components: a carbon dioxide trap, a compound fungicide, a plant growth regulator, and a solvent. The mechanized transplanting method for dual-purpose rice-oilseed trays includes seed drying, disinfection, substrate preparation, tray sowing, darkening treatment, and seedling management. This invention optimizes the concentration, ratio, and frequency of seed coating agent components with those of seedling fertilization, achieving robust rapeseed seedling cultivation. It is suitable for rice and rapeseed seedling cultivation in rice-oilseed rotation areas, solving the problem of incompatible transplanting equipment for rice and rapeseed mechanized transplanting. It has advantages such as low seedling cost, simple process, high qualification rate, and suitability for large-scale production.

The utility model relates to the field of jack fruit breeding devices, and discloses a jack fruit seedling breeding device which comprises a base, the top side of the base is fixedly connected with a plurality of connecting rods, the top sides of the connecting rods are fixedly connected with a seedling raising platform, and the top side of the seedling raising platform is provided with an irrigation groove. A plurality of seedling raising holes are formed in the bottom side of the irrigation groove, seedling raising assemblies are arranged in the seedling raising holes, and a motor is installed in the base. According to the seedling raising device, the seedling raising clamping plates are closed by rotating the rotating shaft, seedlings and soil can be rapidly fixed, the clamping plates are prevented from being opened by hole position limitation after the seedlings are put into the seedling raising holes, and the clamping process in the initial seedling raising stage is simplified. During transplanting, the motor drives the screw rod to drive the lifting platform and the abutting column to eject the seedling culture clamping plate, manual digging is not needed, damage to root systems is avoided, transplanting efficiency is remarkably improved, the method is particularly suitable for large-scale seedling culture scenes, and labor cost and operation loss are reduced.

The invention discloses a cubilose fruit grafting seedling raising method, and belongs to the technical field of fruit tree cultivation. The method comprises six aspects of stock planting field establishment, stock seedling raising, stock water and fertilizer management, grafting, grafted seedling water and fertilizer management and grafted seedling field management. A special cutter tool for cubilose fruit grafting is adopted, an L-shaped section can be formed, the section is smooth and good in integrating degree, and the grafting survival rate and the grafting efficiency can be improved. According to the invention, the seedling raising grids are used for stock seedling raising, so that the seedling raising cost can be saved, and the space utilization rate can be improved. According to the method, the thorn-free huanglong and the argentodoxa cuneata are adopted as the stocks, the root systems are developed, the morbidity of root-knot nematodes can be reduced, the grafting survival rate and the growth vigor are improved, and meanwhile the canker resistance of plants is improved; the quality of the rootstock is guaranteed, the grafting growth vigor is improved, bud germination is promoted, and fruit bearing is carried out in advance by optimizing the length, the period and the number of bud points of the rootstock.

The utility model discloses a novel paper pot chain type seedling sowing device, include: support, movable frame, movable frame slip setting in the top of support, separation box, separation box rotates to be located above the support, the middle part of support is provided with the locating plate, one side of separation box is provided with negative pressure unit, the middle part of locating plate is equidistant and is provided with the locating hole, is used for through negative pressure unit and is fixed with seed adsorption, the utility model has the beneficial effects that: through the cooperation of the overturning of separation box and negative pressure unit, the automatic adsorption and positioning of seed are realized, and the manual operation is reduced, and the repeated overturning separation box can fill the locating hole quickly, compared with traditional manual sowing mode, the speed is faster, can satisfy the demand of large -scale seedling sowing, the locating hole that equidistant is opened on the locating plate can ensure that seed is accurately adsorbed in the specified position, can also guarantee the position accuracy when falling into the floating disc planting area subsequently, improves the uniformity and accuracy of sowing, is favorable to the neat growth of seedling.

This invention discloses a grafting propagation method for the summer wax plum 'Hongyun'. The method involves applying nitrogen fertilizer, boron fertilizer, and humic acid in the autumn of the previous year to build up energy reserves. In early March of the same year, a compound hormone of GA3+6-BA+NAA is sprayed three times. Combined with black plastic film wrapping to increase temperature and block light, black plastic film mulching to retain moisture, and ridge planting with frequent water management, the cambium layer of the wax plum rootstock and summer wax plum scion branches becomes active and ready for peeling in early spring. At this time, large-block budding is performed, resulting in high scion utilization. The buds sprout in early April, and the scions can be ready for transplanting in November of the same year. This method achieves a grafting survival rate of over 82%, which is more than 16 percentage points higher than traditional summer budding. The transplanting rate in the same year reaches 88%, the seedling cycle is shortened by one year, and the scion utilization rate is increased by 110%. This provides reliable technical support for the large-scale propagation of the rare new variety 'Hongyun'.

This invention provides a method for cultivating water-tolerant pond cypress seedlings based on a combined forest-water function, including seed collection and storage, tidal flat sowing, water management, and transplanting at the appropriate age. This invention collects pond cypress seeds that have fallen onto the water surface and subjects the seedlings to intermittent flooding acclimatization during the water management period. This results in seedlings with stronger flood tolerance than traditional seedlings, a shorter acclimatization time after planting, and increased water depth. This method is simple to operate, has low seedling costs, and high seedling survival rates, making it of significant application value in alleviating urban ecological land use constraints.
