The invention discloses a planting method capable of preventing rhubarb from bolting, and belongs to the technical field of Chinese herbal medicine planting. The planting method comprises the steps that the rhubarb and soybeans are interplanted, topdressing is combined, processing is performed with plant chlormequat chloride and garlic water, summer seedling is performed with seeds produced by three-year-old rhubarb, and the transplant depth is strictly controlled at 33-35 cm. According to the planting method, the rhubarb and the soybeans are interplanted, the soybeans have the nitrogen fixation function and compete with the rhubarb for nitrogen nutrition, the nitrogen nutrition supply of the rhubarb is reduced, nitrogen serves as a photosynthesis site of many kinds of enzymes and can improve the photosynthesis efficiency, and therefore the photosynthesis efficiency of the rhubarb is reduced; meanwhile, temperature control is combined, and therefore the rhubarb is effectively prevented from bolting.

The invention discloses a greenhouse grape dense-planting and high-yield early maturing cultivating method. The cultivating is performed in a vegetable greenhouse, and seven measures, such as new seedling dense planting, fertilizer and water management, trimming management of fruiting mother vines, trimming management of fruiting vines, management of grape ears, later-stage management of a grape garden, and management after fruit ear harvesting, are taken. The greenhouse grape dense-planting and high-yield early maturing cultivating method has the advantages that the single-stem and fewer-main vein grape sparse planting mode in the traditional shed frame, fence frame and T-shaped fence frame or the existing greenhouse is replaced into the greenhouse vegetable type high-density planting mode, so the grape stereo structure is simplified, the grape is cultivated in a vegetable greenhouse cultivating way, a single-branch fruiting structure mode is formed, the space structure is sufficiently utilized, the problem of unbalance growth of grape is solved, the yield contradiction between the number of grape plants and the group is solved, and a new cultivating mode with stable and high yield and annual yield exceeding ten thousand kilograms per mu is realized.

The invention discloses a pruning method for promoting the differentiation of blueberry flower buds under the condition of open-ground substrate cultivation. The pruning method is to prune the blueberry plants within 10-15 days after the blueberry fruits are picked in summer: Keep 1-3 basal branches with a thickness of 10mm-30mm as the main trunk; (2) Secondary branch pruning: select secondary branches with a thickness of 5mm-10mm and keep 5-10 branches in total; (3) Tertiary branches Pruning: Select three branches with a thickness of 2mm to 5mm for light or moderate pruning. The present invention can effectively control vegetative growth, promote flower bud differentiation and improve flower bud quality by performing post-fruit pruning on potted blueberries in the open ground, and the annual cycle operation can timely remove old branches and renew the tree body, so that the plants are in a high-yield state every year.

A mosaic kohlrabi seed-keeping method comprises the steps of (1) sowing: soil working and sowing at the end of August; (2) transplanting: transplanting when the seedling age is 27-30 days, and removing the mutation when planting; (3) management: applying composite fertilizer when the yellow leaves fall off from the live seedling to be transplanted and new leaves grow, and spraying the seedling after transplanting by mixing 20 g imidacloprid with 15kg water; (4) re-planting: at the first ten days of December when dark frost comes, pulling out the mosaic kohlrabi and sunning it for one day; cutting off the leaves when planting on the second day, and transplanting it to the field edge or corner where white radish grows nearby; (5) harvesting: at the early June next year, pulling out the mosaic kohlrabi plant and putting it somewhere shelters from the rain; and threshing after ripening, shell removing, drying and collecting. According to the invention, the mosaic kohlrabi is pulled out for sunning for one day, then planted again, therefore the plant can grow from nutrition growth to reproduction growth; the mosaic kohlrabi is planted being mixed with white radish, therefore the anthesis can be postponed more than half a month, and the mosaic kohlrabi is prevented from mixed pollination with other cruciferous crops and avoiding biological hybrid.

The invention provides CpFT gene of wintersweet and its application in flowering regulation. The gene sequence of Wintersweet CpFT provided by the present invention is shown in SEQ ID No.1. The invention firstly clones and obtains the CpFT gene of Wintersweet, and verifies the function of the gene in plant Arabidopsis through transgenic technology. The results showed that the higher the expression level of CpFT gene in Wintersweet, the fewer rosette leaves of transgenic Arabidopsis thaliana, and the shorter the scape time, the first flower opening time, and the first fruit pod formation time. As the time of plant transformation from vegetative growth to reproductive growth is advanced, the vegetative growth time is shortened, the number of rosette leaves is reduced, and the flowering time is advanced. It indicated that the CpFT gene of Wintersweet can promote flowering and inhibit the vegetative growth of the plant, and this gene plays an important role in the process of breaking the dormancy of wintersweet flower buds at low temperature and leading to flower expansion and opening.

The invention discloses a southern winter-jujube cultivation method, which is to trim the jujube tree to be a high-stem dwarf-crown open-center tree form that is suitable to be cultivated in the South and to control the height of the trunk stem; three strong main branches are reserved; three to four supplementary main branches are reserved on the main branches; the main branches are stretched before the flowering; two to three jujube shoots are reserved as a nutrition branch or a renewing branch for every jujube tree; the branches are topped when the jujube shoot has four to five secondary branches; the secondary branches are topped when the secondary branches are grown into 15 to 25 centimeters; the shedding shoot of the jujube is controlled between 20 to 50 cm; two to three shedding shoots of the jujube are reserved for every spur of jujube; the small shedding shoots of jujube on the trunk stem and on the main branches are removed and the adventitious bud sprouted at the base of thejujube tree is removed; two days before the full flowering stage, the trunk stem is stripped or cut circularly. Adopting the invention, the main branches of the tree crown are opened, ventilated and transmitted and are layered, thereby reducing the insect harm and effectively improving the fruit rate; the winter jujube in the South has high yield; the yield of the four-year-growth apple winter jujube can reach 1887 kilograms per Mu and the yield of the three-year-growth Zhanhua winter jujube can reach 980 kilograms per Mu.

The invention discloses application of tomato gene SISAUR58 in controlling tomato growth and drought resistance. It is discovered through series of experiments discover that by overexpression of SISAUR58 gene in two different tomato genes Micro-Tom and Ailsa Crag, all plants are dwarfed with the quantity and area of leaves significantly reduced and drought resistance improved, while by inhibitingSAUR58, nutrient growth of plants can be accelerated. A method established herein is applicable to tomato, not limited to its growth and resistance control, and is applicable to the increase of plantbiological yield and creation of novel drought-resistant varieties.
