一种核桃膨大期追施肥及其制备方法技术

本发明专利技术属于肥料技术领域，为了及时满足核桃树落花坐果后幼果发育膨大等生理活动需要的大量营养物质，使果树在幼果膨大期叶片光合效率提高，养分积累，促进幼果迅速发育膨大减少落果，提供了一种核桃膨大期追施肥及其制备方法。其中各有效成分的重量百分含量为：氮10‑15%、磷3‑6%、钾10‑20%、钙0.1‑1%、硫0.1‑0.8%、镁0.5‑1%、硼0.2‑0.5%、腐殖酸8‑10%；本发明专利技术配比符合果实膨大和花芽分化期间生理活动需求养分的规律，能够促进幼果快速发育迅速膨大，减少生理落果；增强叶片光合效率，增加养分积累，促进新梢生长，保证当年以及次年丰产。可配合微灌系统施用，提高吸收率，避免浪费和土壤残留，生产工艺简单，成本低，适宜于工业化生产。

A Method of Topdressing Fertilizer for Walnut at Expansion Stage and Its Preparation

The invention belongs to the field of fertilizer technology. In order to meet the needs of a large number of nutrients for physiological activities such as the growth and expansion of young fruits of walnut trees after falling flowers and setting fruits in time, the photosynthetic efficiency of leaves of walnut trees during the period of young fruit expanding is improved, nutrient accumulation is promoted, the rapid growth and expansion of young fruits is promoted, and the fruit dropping is reduced, a top-dressing fertilization method and its preparation method during the period of walnut expanding are Among them, the weight percentage content of each effective component is: nitrogen 10_15%, phosphorus 3_6%, potassium 10_20%, calcium 0.1_1%, sulfur 0.1_0.8%, magnesium 0.5_1%, boron 0.2_0.5%, humic acid 8_10%. The formulation of the present invention conforms to the law of nutrient demand of physiological activities during fruit expansion and flower bud differentiation, and can promote rapid growth of young fruit and reduce physiological fruit drop; and enhance photosynthetic efficiency of leaves. Increase nutrient accumulation, promote shoot growth, and ensure high yields in the current year and next year. It can cooperate with the application of micro-irrigation system, improve the absorption rate, avoid waste and soil residue, has simple production process and low cost, and is suitable for industrial production.

技术介绍
果树施肥是保证果树达到丰产、稳产、优质的重要措施之一。多年来，我国的农业高产主要靠施用大量化肥，很多土壤养分的偏重以及微量元素缺乏,导致出现土壤盐渍化板结和缺素症。如缺锌，导致叶小而黄，卷曲，严重时全树叶子小而卷曲，枝条顶端枯死；缺锰，叶子失绿，叶脉之间变为浅绿色，叶肉和叶缘发生枯斑点，易早落；缺硼，枝梢向下枯萎，小叶叶脉间出现棕色浊点，小叶易变形，幼果易脱落；缺铜，常与缺锰同时发生，主要表现为核仁萎缩，叶片早黄脱落，小叶表皮发生黑死斑点，严重的造成枝条死亡。国内外公认的高等植物所必需的营养元素有16种。它们是碳、氢、氧、氮、磷、钾、钙、镁、硫、铁、硼、锰、铜、锌、钼、氯。之所以称这些元素为必需营养元素是因为缺乏这十六种元素植物就不能完成其生命周期。这些营养元素在植物体内的含量相差很大,一般可根据植物体内含量的多少划分为大量营养元素和微量营养元素。大量营养元素含量一般占干物质重量的0.5%以上，它们是碳、氢、氧、氮、磷、钾；中量营养元素的平均含量占干物重在0.1%-0.本文档来自技高网...
