Watermelon seedling culturing substrate and application thereof

InactiveCN102138499AQuality improvementSolving nutritional problems at seedling stageAnimal feeding stuffCultivating equipmentsDiseaseNutrient solution
The invention belongs to the technical field of agriculture and discloses a watermelon seedling culturing substrate, which comprises the following components: earthworm cast, vermiculite, pearlstone and paclobutrazol, wherein the volume ratio of the earthworm cast to the vermiculite to the pearlstone is (2-3):0.6:0.4; and the dosage of the paclobutrazol is between 10 g/m<3> and 20 g/m<3>. When the substrate is used for culturing watermelon own-rooted seedlings, a nutrient solution does not need to be replenished, the seedlings are in order and strong without growing excessively, and the root systems are developed. After the substrate is planted into soil along with the seedlings, beneficial microorganisms in the substrate can quickly form a dominant microflora around the rooting zone of a crop, so that nutrition elements in the soil can be activated, and the utilization ratio of a fertilizer is increased; the application amount of an inorganic fertilizer can be reduced by 20-30 percent; soil-borne diseases can be resisted effectively, the incidence rate of field blight is low, and the control effect is between 86.74 percent and 89.4 percent, is higher than the control effect of an efficient bactericide for an own-rooted seedling growing from the ordinary substrate, and is basically close to the control effect of a grafted seedling; and the soluble sugar content of watermelon and the yield are increased.

Green biological water-flush fertilizer

The invention discloses a green biological water-flush fertilizer, relating to fertilizers. A manufacturing method is as follows: a, adding animal protein powder, vegetable protein powder, complex bacteria and complex enzyme into an amino acid solution, mixing uniformly, placing the mixture under the temperature of 15-35 DEG C, and after 6-8 days, forming a product A; and b, adding a complex nutrition conditioner, a continuous cropping modifier, a biological insect repellant, a harm removing agent, trace elements, a nitrogen-phosphorus-potassium compound fertilizer into the product A, mixing uniformly and obtaining the green biological water-flush fertilizer. The green biological water-flush fertilizer has the beneficial effects that 1, the sprouting rate can be improved, the fast rootingcan be realized, the sufficient nutrition of plants can be ensured, and premature senility resistance and aging resistance are achieved; 2, the yield and the quality of vegetables, melons and fruits are improved; 3, the utilization ratio, the long-term property, fast effect, long effect and stable efficiency of a base fertilizer are improved; 4, the extremely-good inhibiting effect and improving function are achieved for yellow seedlings, runt seedlings, lobules, leaf roll, blight, pythium debaryanum, droop, dead seedling, rot roots, abnormal rotting disease, virus disease, seedling falling disease and the like; and 5, green and unpolluted foods are beneficial to being produced.

SNP loci linked with blight resistant gene Fon-1 in watermelon, and markers thereof

ActiveCN103146691AShorten the timeTo achieve the purpose of assisted breedingDNA preparationDNA/RNA fragmentationResistant genesTest material
The invention relates to the fields of gene sequences and acquiring methods thereof, and concretely relates to SNP loci linked with a blight resistant gene Fon-1 in a watermelon, markers thereof, and acquiring methods of the loci and the markers. The SNP loci linked with a blight resistant gene Fon-1 in a watermelon and the markers thereof have nucleotide base sequences represented by SEQ ID NO:1-8 in a sequence table. The acquiring method of the loci comprises the following steps: 1, selecting a tested material; 2, carrying out preliminary positioning of the blight resistant gene Fon-1 in the watermelon; 3, acquiring candidate SNP; and 4, acquiring the SNP loci closely linked with the blight resistant gene Fon-1 in the watermelon, and verifying the candidate SNP loci. According to the invention, the phenotype identification and the molecular detection of F2 generation separation populations and natural populations are carried out through utilizing a series of markers to confirm the close linkage degree of the series of the SNP loci with target properties; and the SNP loci are utilized to design the markers respectively, and the markers can be utilized to carry out the initial-stage screening of the kind in order to reach a molecule assisted breeding purpose, so the breeding period is substantially shortened, and an important scientific research meaning is possessed.

Planting method for regulating and controlling continuous cropping obstacles of atractylides macrocephala koidz

ActiveCN102165892AReduce morbidityImprove seedling retention rateHorticultureContinuous croppingRoot rot
The invention discloses a planting method for regulating and controlling continuous cropping obstacles of atractylides macrocephala koidz, which comprising the following steps of: applying 40 to 100g of lime nitrogen to each square meter of a continuous cropping field, performing deep tillage, watering soil by using 500 to 1,000 times of prochloraz or fluazinam, covering by using a thin film for 15 to 20 days, uncovering the thin film, ventilating for 10 to 15 days, and planting the atractylides macrocephala koidz and applying 0.5 to 3.5kg of biological organic fertilizer per 5 square meters; and irrigating the root of the atractylides macrocephala koidz once by using 500 to 1,000 times of the prochloraz or the fluazinam or hymexazol before disease outbreak in June and July; or the planting method comprises the following steps of: ploughing and covering the thin film after the crop rotation of spring corn, irrigating until water is above the soil surface, keeping hermetic for 20 to 90 days, and uncovering the thin film to plant the atractylides macrocephala koidz. By the planting method, the incidence rate of diseases such as root rot, southern blight and the like of the atractylides macrocephala koidz is reduced greatly, the seedling survival rate of the atractylides macrocephala koidz is improved, and the yield of atractylides macrocephala koidz rhizomes is improved. Simultaneously, the utilization rate of land can be improved to improve economic benefits.

Herbahouttuyniae cultivation method

The invention relates to the technical field of traditional Chinese herbal medicine cultivation, in particular to a herbahouttuyniae cultivation method, which comprises the following steps of: 1) determining a planting time: planting seedlings at a period from the middle ten days and last ten days of September to the first ten days of November every year; 2) determining a planting mode: selecting high-stalk crops for interplanting; 3) preparing the seedlings: conducting asexual reproduction by using subterraneous stems of herbahouttuyniae as reproduction materials; 4) planting the seedlings: directly placing the seedlings on compartment surfaces and covering the compartment surfaces with rice straw or maize stalks after the seedlings are planted; 5) conducting field management: removing weed at the growth period of the herbahouttuyniae, removing ill herbahouttuyniae plants, weak herbahouttuyniae plants and non-herbahouttuyniae crops during weeding, and making sure that the herbahouttuyniae is not damaged; and during top dressing, using farm manure as main fertilizers and chemical fertilizers as auxiliary fertilizers, paying attention to reasonable drainage and irrigation and keeping soil wet at the entire growth period of the herbahouttuyniae; and 6) harvesting at a proper time and the like. By adopting the herbahouttuyniae cultivation method, the yield of the herbahouttuyniae is high, the damage by diseases and insects is reduced, the herbahouttuyniae diseases such as southern blight and zonate spot can be effectively prevented and controlled, and the yield of the herbahouttuyniae and the mass content of medicinal components in the herbahouttuyniae are improved to the utmost extent.
