Seedling substrate for soilless culture for vegetables

The invention discloses a seedling substrate for vegetables, belonging to the technical field of soilless culture. The substrate formula comprises the following components based on volume ratios: 10-40% of fermented vinegar dreg, 5-30% of fermented cassava dreg, 5-30% of plant ash, 5-30% of perlite, 5-30% of vermiculite and 10-25% of turf. The water content of the substrate is not bigger than 50%, and the total porosity of the substrate is 65-95%, and the total nutrient content of the substrate (N+P2O5+K2O) is 3-5%, and the grain diameter of the substrate is 0.1-4.9 mm, and the volume weight of the substrate is 0.2-0.8 g/cm3, and the gas-water ratio of the substrate is 1: 2-4, and the EC (elastic coefficient) value of the substrate is 1-3 and the pH value of the substrate is 5.8-7.5. The seedling substrate for soilless culture for vegetables mainly uses organic wastes as raw materials, and produces seedling substrate by high temperature fermentation treatment, and changes wastes into wealth, and turns harm into good. The invention has a low production cost, a light weight and complete nutrients such that it is suitable for growth and development for vegetable seedlings, and is a good substrate for soilless culture industrialized tray seedling for vegetables.

Domestic full-automatic vegetable planting machine

The invention relates to a domestic full-automatic vegetable planting machine. The domestic full-automatic vegetable planting machine comprises a machine box. A planting tray which is used for plantation of vegetables and enabling the vegetables to grow is arranged in the machine box. A nutrient solution conveying and adjusting system which is used for adjusting and controlling a nutrient solution in the planting tray, an environment control system which is used for adjusting the growing environment in the machine box, and an environmental state detection device which is used for detecting the environmental state in the machine box are further arranged in the machine box. The input end of the environment control system is connected with the environmental state detection device, the output end of the environment control system is connected with the nutrient solution conveying and adjusting system, the environment control system adjusts and controls the environmental state of the planted vegetables in the machine box according to the environmental state detected by the environmental state detection device, and the nutrient solution in the planting tray is adjusted through the nutrient solution conveying and adjusting system so that the requirement for planting the vegetables inside a house can be met. The domestic full-automatic vegetable planting machine is compact in structure, convenient to use, capable of meeting the requirement for planting the vegetables inside the house, wide in application range, low in cost, safe and reliable.

Single disc liquid fertilizer opener

ActiveUS20070044694A1Minimize opportunityEliminate premature mechanical failureTill seedingPlantingForce structureCircular disc
A method and apparatus to be mounted upon a planter row unit for delivering liquid fertilizer to the bottom of a trench without contacting the seed to be planted is disclosed and claimed. The system as claimed and described is adapted for mounting to substantially all modern row units employing floating row units. The method and apparatus as described does not interfere with existing down pressure or seed placement systems as found on modern row crop planters. As described and implemented, the method and apparatus is more compact and lighter in weight than the prior art. The attached assembly for a seed planting unit works in combination with a seed trench opener to form a trench for the deposit of liquid fertilizer offset from and parallel to the later formed seed trench. The apparatus allows directed liquid fertilizer delivery in close proximity to the seed trench with minimal disruption of said seed trench. The attachment includes a single disk blade disposed forward of the seed trench forming unit. The single disk blade is disposed at an angle of four degrees or less from the line defining the direction of travel of the seed planting implement in combination with a furrow strap. The attachment includes a selectively adjustable down force structure and a selectively adjustable depth control mechanism.

Nitrogen fertilizer compound synergist and preparation method

The invention relates to nitrogen element fertilizer, in particular to a nitrogen element fertilizer composite synergist and a preparation method thereof. The composite synergist consists of a biochemical inhibitor, a synergist, a nitrogen element stabilizer, a carrier and microelements, the weight portion ratio of the materials is 1:0.01-1: 0.01-0.5: 0.5-1: 0-0.05, wherein the biochemical inhibitor can be a nitrification inhibitor and a urease inhibitor, the synergist can be poly-aspartic acid, and the nitrogen element stabilizer can be hydrolyzed amino acid, humic acid, alginic acid or alginic acid water soluble salt. The preparation method comprises the following steps: crushing the raw materials, screening the raw materials with a sieve of 30 to 100 meshes, and stirring and mixing the raw materials according to the proportion. The nitrogen element fertilizer composite synergist is suitable for growing long acting nitrogenous fertilizer taking urea or ammonium nitrogen fertilizer as raw materials and can be applied to various soils together with urea or ammonium nitrogen fertilizer so as to effectively prolong the fertilizer efficiency period of the urea or the ammonium nitrogen fertilizer. The fertilizer efficiency period can reach 100 to 120 days. The nitrogen element fertilizer composite synergist has remarkable resistance to diseases, drought and lodging, effectively improves the capability of soil to reserve nutrients, and has good effects for off-season crops.
