Paddy rice sprout cultivation controlled release fertilizer and rice seed contact fertilizing apparatus

Abstract

The invention relates to a paddy rice sprout cultivation controlled release fertilizer and a rice seed contact fertilizing apparatus, the rice seed contact fertilizing apparatus comprises a casing, the casing is divided into a seed chamber and a fertilizer chamber through a vertical baffle plate, the bottom of the casing is connected to a rotation shaft in a rotation mode, a driving gear and a travelling wheel are fixed on two ends of the rotation shaft at intervals, the travelling wheels are positioned on a vertical track of a rectangular track frame having four rollers, bottoms of the seed chamber and the fertilizer chamber are respectively connected to the rotation shaft in a rotation mode, a driven gear is connected to two ends of two rotation shafts through an overrunning clutch; wherein two driven gears at one side of the casing are simultaneously engaged with the driving gear, two driven gears at other side of the casing respectively pass through a transition gear and are simultaneously engaged with the driving gear, two transition gears are respectively connected to the casing in a rotation mode, a push-pull rod is fixedly connected to front part of the casing; and a narrow seam as a discharge hatch is respectively arranged at bottom of the seed chamber and the fertilizer chamber.

Description

Technical field [0001] The invention relates to an agricultural machine, in particular to a rice seedling raising controlled-release fertilizer and a rice seed contact fertilization device. Background technique [0002] Farmers are accustomed to raising seedlings on rice seedling trays: the size of the plastic seedling trays used is 580×280×28 mm; the operating procedures: (1) spread the plastic seedling trays in the plastic greenhouse; (2) cover the nutrient soil after adjusting the acid In the seedling raising tray; (3) Evenly soaked rice seeds; (4) Covered with a layer of acid-adjusted nutrient soil; (5) Sprinkler irrigation; (6) Covered with breathable film; (7) To compensate If the nutrient soil is insufficient, apply ammonium sulfate 1-2 times 5-7 days before getting up, totaling 60-70 grams per square meter. Existing problems: The habit of applying ammonium sulfate in the late stage of raising seedlings will affect root development, and the seedlings are prone to disease,...

AI Technical Summary

Problems solved by technology

Existing problems: topdressing ammonium sulfate in the later stage of habitual seedling raising, poor grasp will affect root development, seedlings are prone to diseases, and then affect the growth of rice field; fertilization method during the growth period of rice field using customary seedling raising: base fertilizer + three topdressing fertilizers; serious loss of nitrogen fertilizer, low utilization

At present, the contact fertilization of S-type controlled-release fertilizer is basically mixed with substrate or nutrient soil in a small amount of experiments; but in large-scale applications, because the specific gravity of 2-4mm granular controlled-release fertilizer is smaller than that of nutrient soil, it cannot be mixed. Uniform or easy to stratify, resulting in the controlled-release fertilizer in the surface soil of the seedling tray being easily spilled and lost when the seedlings are rolled up and planted
