The technical characterstic of special-purpose control-release fertilizer for peony of the present invention is that the nutrient controlled-release effect of thermoplastic resin membrane wrapping fertilizer is good, is not subjected to the influence of moisture in the soil water-containing weight range of tree peony suitable growth, and nutrient supply is stable.And the membrane wrapping thickness difference, the controlled release asynchronism(-nization).Tree peony growth time in a year is long, needs sufficient and stable nutrient supply.Single thermoplastic resin membrane wrapping fertilizer of planting that difference is discharged the period carries out compositely, can accurately control nitrogen, phosphorus, potassium and discharge by requirements of tree peony growth nutrient absorbing rule in different periods, and applied once can satisfy the tree peony needs whole year.
Excellent results of the present invention is as follows:
1. nutrient element releasing rule is consistent with the tree peony dietetic alimentation
The root of tree peony, stem have the ability that stores nutrient, and the nutrition that is used for leaf bud, flower bud germination spring absorbs the continued growth of nutrition supply flower and leaf gradually mainly from storing nutrient from soil to preceding 15～20 talentes of blooming.At this moment the nutritive element of Xi Shouing is based on nitrogen.Begin the vigorous growth of bud differentiation and stem, leaf the mid-May of Xie Huahou to June, need provide sufficient and stable nitrogen, phosphorus nutrition, particularly phosphorus element.Needing nitrogenous fertilizer more period in the tree peony 1 year is autumn, to guarantee the photosynthetic efficiency of blade, makes more nutrition and is stored in root, the stem.Tree peony is less relatively to the absorption of potassium, but the additional a certain amount of potash fertilizer of spring and early summer is useful to strong degree and the resistance against diseases that improves the tree peony branch.Special-purpose control-release fertilizer according to the nutritional needs rule design of tree peony, can satisfy its high yield and high quality requirement just.
2. nutrient supply is stable, improves the quality of flower
Practice shows that growing that Tree Peony flower is good needs stable and competent nutrient supply, and the too big color to flower of the fluctuation of soil nutrient content, shape etc. all have influence in various degree.The quick-acting chemical fertilizer is subjected to the restriction of fertilizer application frequency because the back dissolving that is manured into soil is fast, is difficult to accomplish that the soil nutrient supply is steady.Special-purpose control-release fertilizer is fertile composite the forming of single kind controlled release by multiple different release periods, their nutrient release profiles is through repeatedly stack, on the big period, guarantee the tree peony nutrient requirement of each breeding time, in the short relatively time, make nutrition supply steady again, thereby reach the purpose of high yield and high quality.
3. avoid repeatedly applying fertilizer injury to the tree peony spray
Tree peony is at growing period, and the space is airtight relatively, and the branches and leaves delicacy is easy to break, the field operational difficulty.And apply fertilizer at every turn except that spreading fertilizer over the fields fertilizer, also need hoe the fields so that fertilizer and mixing with soil have more increased the probability of damaging branches and leaves.Special-purpose control-release fertilizer is to use before the tree peony rudiment in spring, and this time space is relatively large, is convenient to operation, and needn't goes later on again and topdress, and therefore can obviously reduce the infringement to spray.
