Cultivation method of dendrobium candidum

ActiveCN101999290AAdvantages of cultivation methodSafe and efficient cultivationWatering devicesCultivating equipmentsWater filterRoot growth
The invention relates to a cultivation method of dendrobium candidum, comprising the following steps of: paving the ground: levelling a land, and then sequentially paving a quicklime powder layer, a gardening ground cloth, a gravel layer and a shading net layer from bottom to top; forming rectangular land; building a shed; selecting the specifications of species and germchits: selecting seed sources in Zhejiang and domesticated seedlings obtained by domesticating tissue culture seedlings transplanted out of bottles for more than one year; and culturing. In the invention, the layers of multiple-layer ground pavements are not mutually influenced, the gravel layer can be used as a water filtering layer to provide a good root growth environment for the dendrobium candidum, and the multiple-layer ground pavements also physically obstruct insect pest sources from underground to a peripheral space with a matched insect prevention measures together, thereby not only saving the cost by reducing the use amount of pesticides, but also greatly enhancing the edible safety of the dendrobium candidum. The cultivation method of the dendrobium candidum creates an optimal environment for the growth of the dendrobium candidum from roots and the ground aiming at the artificial cultivation of a rare and endangered traditional Chinese medicinal material, i.e. the dendrobium candidum, and is used for carrying out pest control by adopting a full-physical method, thereby effectively reducing the generation of plant diseases and insect pests and realizing the safe and efficient cultivation.

Saline-alkali soil conditioner

InactiveCN104591926AImprove deficiency symptomsEnhance salt-alkali resistanceSuperphosphatesMagnesium fertilisersPlant rootsSodium Bentonite
The invention relates to a composition for improving soil, in particular relates to a saline-alkali soil conditioner. The saline-alkali soil conditioner is prepared by mixing the following components by weight percent: 20%-35% of sulfur powder, 20%-30% of humic acid, 5%-10% of bentonite, 20%-25% of magnesium sulfate heptahydrate, 8%-12% of calcium superphosphate, 1%-2% of zinc sulfate heptahydrate and 2%-3% of boric acid. The saline-alkali soil conditioner can be used for regulating acid-base level of the soil, and effectively supplementing microelements in the soil, improving the nutritional deficiency symptom of crops, chelating harmful heavy metal elements in the soil, reducing saline and alkali degree, promoting the soil to form a granular structure, improving root growth environment of crops, enhancing saline and alkali resistance of crops, disease resistance and cultivation of resilience, reducing the harm of saline and alkali to plant roots, and releasing the effective phosphorous solidified by the soil, increasing soil fertility, holding water and saving fertilizer so as to finally and completely improve the soil, recover the soil fertility, increase both production and income and improve crop quality and utilization rate of the fertilizer.

Multifunctional high efficient organic material decomposition agent and preparation method thereof

The invention discloses a multifunctional high efficient organic material decomposition agent and a preparation method thereof. The decomposition agent of the invention comprises composite original strains consisting of bacillus amyloliquefaciens, Aspergillus oryzae, Trichoderma viride, and Saccharomyces cerevisiae and an organic material carrier, and an inorganic carrier. Strains of the decomposition agent can be mutualistic, and have complementary advantages. The adaptation is wide, and a plurality of organic matter clastic enzymes can be produced by metabolism. The decomposition agent has high activity and can be used for fermentation and conversion of a plurality of organic materials such as livestock and poultry excrements, crop straws, city sludge, food waste, food processing and pharmaceutical waste residues, and has fast fermentation start, fast deodorization, low temperature resistance, and low moisture resistance. The fermentation period is shorter by 5-7 days than that in the same technology. Fermented and converted organic fertilizers have the obvious rhizosphere ecological regulation and control function, promote the root growth, and improve the root vitality. A plurality of soil borne diseases are prevented by improving the flora diversity, hyperparasitism and biological antagonism.

Method for evaluating flooding tolerance of maize variety

The invention discloses a method for evaluating flood tolerance of the maize variety. The method comprises the following steps of 1, after a pot is drowned, performing evaluation on four indexes, such as the color of a leaf, the form of the leaf, the color of a stem and the form of a root to preliminarily determine the flooding tolerance level; 2, performing two-sample pairing statistic analysis method on 15 shapes subjected to preliminary screening in the first step, and taking the strain height, the net photosynthetic rate, the green area, the root biomass, the root growth rate, the content of chlorophyll a, the total content of chlorophyll and an SPAD (soil and plant analyzer development) value as flood tolerance degree evaluation indexes according to the waterlogging influence degree; and 3, performing clustering analysis on the authentication indexes obtained by the second step, and classifying the varieties with different flood tolerance degrees into a flood tolerance hybrid and a non flood tolerance hybrid near to 27 according to genetic distances of all property clusters. The method for quickly and easily obtaining the flood tolerance evaluation indexes in a maize seedling stage is established according to the form change of leaves and stems above the ground as well as the physiologic and morphologic expression of plants, so that a basis is supplied to correct selection of the maize variety in an easily flooding region.
