In an air pressurized system for use in delivering seeds in an agricultural planter from a main hopper to plural remote bins each associated with a respective seed discharge unit, an air / seed mixture is provided to a seed discharge unit via an air pressure dissipator which vents the air to the atmosphere in controlling the rate at which seed is delivered to the seed discharge unit. The air pressure dissipator includes an upper, angled tube having an outwardly tapered lower end adapted to receive an upper end of a perforated screen tube which extends into the seed discharge unit. As the seed discharge unit fills with seed during operation, the air pressure dissipator regulates the air flow entraining and transporting the seed by directing a portion of the air to the atmosphere when necessary to provide seed to the seed discharge unit to substantially match the seed discharge rate.

Insect refuge strategies are described for the management of insect resistance development. The present invention relates generally to the control of pests that cause damage to crop plants, and in particular to corn plants, by their feeding activities directed to root damage, and more particularly to the control of such plant pests by exposing target pests to seeds or mixtures of seeds having multiple different modes of action. The first one or more transgenes and the second one or more transgenes are each, respectively, insecticidal to the same target insect but have different modes of action, and bind either semi-competitively or non-competitively to different binding sites in the target pest. In addition, the treatment of such seed with a chemical or peptide-associated pesticide prior to planting the seed is also disclosed.

A date palm seed lost circulation material (LCM) is provided having a date palm seed admixture of date palm seed particles of various sizes. The date palm seed particles may have a size greater than about 2380 microns in a range of about 40% to about 42% by weight, particles having a size greater than about 595 microns and less than about 2381 microns in a range of about 46% to about 48% by weight, particles having a size greater than about 400 microns and less than about 596 microns in a range of about 4% to about 6% by weight, particles having a size less than about 210 microns in a range of about 4% to about 6% by weight, and particles having a size less than about 149 microns in a range of about 1% to about 3% by weight. Methods of lost circulation control using and manufacture of a date palm seed LCM are also provided.

The invention relates to a bletilla striata seed direct-seeding seedling raising method. Common seedling raising substrate, pesticides and fertilizer sold on the market are mixed, then the mixture is laid on field ridges, the laying thickness is 1-3 cm, the complex steps of producing complex substrate materials and blending substrate are omitted, meanwhile, the consumption of the substrate is greatly decreased, and the cost is saved; bletilla striata seeds, potato starch, rooting powder and an MS dry powder culture medium are mixed in a certain ratio, a seed mixture is obtained, the bletilla striata seeds are incompletely developed in nature and have no endosperms, the potatoes starch, the MS dry powder culture medium and the bletilla striata seeds are mixed to provide nutritional substances necessary for germination of the bletilla striata seeds and are equivalent to endosperms of bletilla striata, the rooting powder serves as plant exogenous hormone to stimulate rooting and germination of the bletilla striata seeds, and the germination rate of the bletilla striata seeds is increased. The method is simple to operate, raw materials are simple and available, the cost is low, the growth cycle is short, and the seed germination rate is high.

The invention relates to a toothed roll type cleaning method and device for shells and seeds of camellia oleifera. The method and the device utilize the interaction of footed rolls to separate the shells of camellia oleifera from the seeds of camellia oleifera. Shell and seed mixtures of camellia oleifera enter into a cleaning separation device from a feed opening in a housing and fall on the upper parts of the toothed rolls; under the rotation of a sweeping screw machine, materials are uniformly spread in the cleaning separation device, and meanwhile the materials are constantly pushed; the seeds of camellia oleifera are separated from the shell and seed mixtures of camellia oleifera under the action of the toothed rolls and enter a shell outlet; the residual seeds of camellia oleifera enter a seed outlet under the action of the sweeping screw machine, and therefore the purpose of the separation of shells and seeds is achieved. According to the method and the device, after the shell and seed mixtures are swept by the sweeping screw machine to be uniformly spread, the seeds of camellia oleifera in the mixtures are grabbed and dragged down and finally leave the inner part of the cleaning device and enter the shell outlet, but the seeds cannot be grabbed due to the larger size and finally enter the seed outlet under the pushing action of the sweeping screw machine. The structure is very conducive to the separation of shells and seeds of the shell and seed mixtures of camellia oleifera with different water contents.
