Technical characterstic of the present invention is to utilize the Nutrient Release of different coated fertilizers, while is according to the law of nutritive absorption of Radix Dauci Sativae, carry out the difference release period of specific coating quantity and the single kind controlled release fertilizer and the conventional fertilizer of part of different fertilizer core accurately composite, formed the special-purpose fertile of Radix Dauci Sativae, and carried out field experiment, obtained good effect.This fertilizer is disposable being manured into soil before carrot seeding, needn't go later on again and topdress.
Excellent results of the present invention is as follows:
1. nutrient discharges and meets Radix Dauci Sativae absorption requirement
The different growth phases of Radix Dauci Sativae have notable difference to absorption rate, the quantity of nitrogen, phosphorus, potassium, and it is very fast that growth is preceding, absorb nitrogen mid-term, and slow down in the absorption of piece root expanding stage; Absorbing state to potassium is that growth is less early stage, and piece root expanding stage absorbs at most; Though the absorption quantity in early stage to phosphorus is few, can not lack, otherwise influence root system development.Special-purpose fertile just according to the absorbing rule of Radix Dauci Sativae to nitrogen, phosphorus, potassium, utilize nitrogen, phosphorus, potassium controlled release fertilizer and the conventional fertilizer of part of different time of releasing to carry out composite forming, can satisfy of the special requirement of the different growth phases of Radix Dauci Sativae nitrogen, phosphorus, potassium three elements.
2. the nitrogenous fertilizer supply is stable, is beneficial to the Radix Dauci Sativae high yield
Radix Dauci Sativae is to be the crop of product with results piece root, and expanding of piece root relies on the photosynthate of over-ground part manufacturing to finish.Nitrogenous fertilizer is too much, and cauline leaf over growth, most of photosynthate are used for self to be built, and is unfavorable for that the piece root expands; The nitrogenous fertilizer deficiency also can make the leaf poor growth, and the photosynthate of manufacturing reduces, and causes the underproduction.The quick-acting nitrogenous fertilizer of using at present can make soil nitrogen raise suddenly after the fertilising, do not apply fertilizer and nitrogen is lacked.Special-purpose fertile nitrogen is slow release of absorbing rule according to Radix Dauci Sativae, can not cause that soil concentration is too high in short-term, and this both can guarantee a certain amount of nitrogen supply, also was unlikely to make the cauline leaf over growth.
3. disposable fertilizer is imposed on the root system soil layer, improve fertilization effect
The root system of Radix Dauci Sativae is different from general crop, and growth its root system in early stage is nearer from the face of land, can absorb the nutrient of topsoil.To the intermediary and later stages, because the expanding and extend of piece root, the root system that mainly relies on the piece roots and tops to grow to nutrient absorbing.These roots bury darker, and the fertilizer that imposes on the face of land is difficult to absorb.Topdressing on producing at present mainly is to spread fertilizer over the fields in the face of land, and be far away apart from root system, particularly for the less phosphorus of movability, potash fertilizer, more is unfavorable for absorbing.Special-purpose fertilizer is disposable prior to seeding executing in root layer soil, and near apart from root system, fertilization effect is good.
4. save labor, save labour cost
Present production gone up the Radix Dauci Sativae fertilising except that base manure, also need topdress 2～3 times, and special-purpose fertilizer adopts single fertilization, greatly reduces peasant's labour intensity, has saved the recruitment cost, has improved economic benefit.
