The invention discloses a Chinese wolfberry seedling raising method for improving paddy field soil, which comprises the following specific steps: collecting cutting slips: collecting branches with the diameter of more than 0.3 cm, cutting the branches into cutting slips with the length of 12-15 cm, and reserving 2-3 tender shoots on each cutting slip without damage; rooting liquid treatment: preparing a rooting liquid, and soaking the positions 3-5 cm above the bottom ends of the cutting slips in the rooting liquid for 12-24 hours; the rooting liquid is mainly prepared from rice vinegar and brown sugar; temperature-controlled root promoting: controlling the environment temperature to be 15-25 DEG C, and vertically inserting the cutting slips treated by the rooting liquid into the seedling raising container; the seedling raising container is filled with improved paddy field soil in advance; when 1-2 tender shoots newly grow on the cutting slips and 7-8 tender leaves grow on the cutting slips, shoot tips are removed, so that the tender shoots on the cutting slips are converted into semi-lignified from fleshy, apical dominance is inhibited, rooting is promoted, and seedling raising is continued; when new buds grow out again, seedling raising is completed, and the seedlings are transplanted to a field for planting. The lycium barbarum seedling raising method has the advantages of being low in cost, environmentally friendly, high in survival rate, suitable for improved paddy field soil and the like.

The present application relates to a kind of side branch changes more main stem shape fruit tree cultivation method, its core technology is: using the top dominance of fruit tree and the characteristics of latent bud sprouting in light, a large number of germination on the transverse auxiliary main branch and lateral branch, branch thick leaf big Zhang fat, so as to realize tree vigor rejuvenation, high quality fruit yield.The present application is through two methods of pulling branch and deleting sparse, cultivate shrub fruit tree lateral branch end distance ground 60-70 cm, arbor fruit tree lateral branch end distance ground 80-120 cm, with the opening angle of ground is 0-30 degrees to form a layer of framework, and sprout 3-4 level small branches to hang fruit.The present application adopts a kind of new shaping pruning cultivation method, after 3-5 years of special cultivation management, the whole tree keeps shrub fruit tree 0.8-1.5 meter high single layer tree crown, arbor fruit tree 1.7-2.8 meter high single layer tree crown, tree crown diameter is 0.5-1 times faster than traditional cultivation method, rapidly forms high yield tree crown, realizes early fruiting, high yield, high quality yield.

The invention discloses a branch twisting method for recycling spindling branches of bee sugar plums, and relates to the technical field of fruit tree cultivation. According to the method, healthy spindling branches are screened, pressing (40-50 DEG C) and branch pushing (10-15 DEG C) are carried out in a specific period, weak branch pruning (1-2 hidden buds are reserved) and subsequent maintenance are combined, apical dominance is effectively eliminated, and flower bud differentiation is promoted. Experiments show that by means of the method, the result conversion rate of the spindling branches in the next year can reach 75% or above, the yield of a single plant is increased by 20%-35%, and the crown structure can be optimized. The method has standardized steps, is suitable for different tree ages, and is convenient for large-scale popularization.

This invention discloses a method and application for promoting root bending and lateral root formation in seed-sown persimmon (Diospyros kaki). This invention belongs to the technical field of persimmon seedling cultivation and bonsai material cultivation. The method includes low-temperature stratification treatment of persimmon seeds; disinfection and imbibition treatment of the stratified seeds followed by sowing in a gibberellin-containing GA3 medium; periodic artificial adjustment of the radicle growth direction when the radicle reaches 1 cm in length to induce taproot bending; removal of 1 cm of root tip when the taproot reaches 4 cm in length to promote lateral root and fibrous root germination; and subsequent hardening-off and transplanting. This invention, by regulating early geotropism of the radicle and taproot apical dominance, enables the taproot of persimmon seed-sown seedlings to form a natural bending shape and significantly promotes lateral root germination, resulting in good ornamental value, growth vitality, and promising application prospects.

The invention belongs to the technical field of plant cultivation, and discloses a bamboo shoot mustard seed production method utilizing lateral branches to bloom and bear pods and application of the bamboo shoot mustard seed production method. The method comprises the following steps: germinating mustard seeds, and then carrying out prolonged illumination seedling raising treatment to obtain mustard seedlings; performing field planting, lateral branch culture, pollination, topping and seed collection on young seedlings of the brassica juncea to obtain seeds of the brassica juncea; the illumination period of illumination seedling culture treatment is prolonged to be 16 h / d to 22 h / d, and the time is 20 d to 40 d. By means of the method, the development process of the bamboo shoot mustard can be accelerated, flower bud differentiation is promoted, the flowering time is advanced, so that the top of the plant loses apical dominance, the bamboo shoot mustard grows into lateral branches for flowering and pod bearing through lateral bud culture, the bamboo shoot mustard does not have large fleshy stems in the flowering period, the probability that the plant is infected with sclerotiniose can be reduced, and the survival rate of the plant is increased. Meanwhile, the effects of reducing sclerotiniose harm and improving the seed production yield are achieved, and the method has huge application prospects in bamboo shoot mustard cultivation and / or planting.

Aiming at the problems of high cost, complex technology, low germination rate, long seedling period and the like caused by dependence on exogenous hormone or tissue culture in the traditional Chinese orchid cultivation technology, the germination rate is increased by comprehensive natural cultivation measures. The method specifically comprises the following steps of: 1, regularly and thinly applying a diluted and decomposed rapeseed cake fertilizer and a water-soluble fertilizer with the concentration of 0.1% o, and promoting nutrient accumulation, increasing the number of leaves by more than 20% and increasing the volume of a reed head by 40% by combining with 0.1% of salt-free bone black with the soil amount of a pot; 2, illumination intensity: controlling the illumination intensity to 9000-18000 lux to enhance nutrient accumulation; 3, inclined planting innovative application: the inclination angle of the plant is adjusted to be 10-85 degrees, the apical dominance is broken, the germination number of a single reed head is more than 3, the seedling germination rate is improved by more than 50%, the orchid without seedlings can germinate, and the comprehensive germination seedling rate is doubled compared with that of a traditional method; 4, using grass carbon with the thickness of 1cm to protect reed heads, and putting a small amount of willow barks on the outer side of the grass carbon;

A new Cannabis variety distinguished by its maturity time, apical dominance, internode length. flower trichome density, aroma. very high THCV:THC ratio, and total cannabinoid content.
