The invention discloses a root restriction culture method for preventing the passion fruit base rot disease, and belongs to the field of plant cultivation. The method comprises the following steps ofvirus-free seedling selection, substrate preparation, canopy frame construction, planting vessel installation and current year cultivation and management. By selecting virus-free seedlings for planting, a special substrate, a special planting vessel and a reasonable biennial culture mode are prepared for solving the passion fruit virus disease from the source, the problem of the passion fruit baserot disease in the planting process is solved, the effect of preventing and treating bacterium breeding is achieved, and the requirement for growth environment needed by passion fruit planting is met. Passion fruit virus disease spreading can be controlled, the base rot disease outbreak tendency can be controlled, and the purposes of high efficiency and high production of passion fruit are achieved.

The invention discloses a kiwi fruit frame-free cultivating method, and belongs to the technical field of plant cultivation. The method includes the following steps of (1), variety selection, whereina female plant variety with short junction spacing is selected; (2), garden establishing and planting, wherein 110-120 plants are planted per mu, the line spacing is 2.5-3 m, and the row spacing is 2m; (3), first year management, wherein in the spring germination period, 2-3 buds are reserved above each junction for severe pruning, after germination, strong single branches are selected and reserved as trunks, pinching is carried out when the trunks grow to 1.2-1.8 m high, when top leaves grow to be mature, the trunks are reserved to be 0.8-1.2 m high in a centralized mode for cutting, and waiting for the trunks to germinate again is carried out; after each trunk germinates, four branches are selected and reserved, wherein the four branches comprise an upright branch, growing upwards, reserved at the top end of the trunk and further comprises three alternate branches, pinching is carried out when the four branches are 0.8-1.2 m long respectively, the alternate branches are reserved tobe 36-45 cm long when the top leaves are mature for cutting, and the branch spacing of secondary branches is kept at 20-25 cm; during winter pruning, bases of the three alternate branches are 8-12 cmlong, lateral buds are reserved for cutting, and the plants grow into kiwi fruit undershrub tree bodies. No shed frame needs to be built, and the cost is reduced.

The invention discloses a method for growing bamboo and willow seedlings in arid areas, which mainly includes sand bed preparation, burying, spraying water, branching and post-branching management. Then the branches are cut off to become individual seedlings, and then cultivated into seedlings under certain water and fertilizer conditions. Compared with the prior art, the present invention builds a micro-environment by sprinkling irrigation to raise seedlings in batches, and the seedlings raised are strong and uniform in size, without rooting agent or rooting powder treatment, but the root system of the plant is more than the seedlings raised by bamboo willow microplant propagation and seedling technology. 2 to 3 roots, so the plants have strong growth, especially the high reproduction coefficient, which is generally more than 8 times that of conventional cutting seedlings. The degree of intensification is high, manpower and material resources are saved, and the emergence rate per unit area is high.
