Description
Technical field
The present invention relates to the synchronous Controlled Release Fertilizer of a kind of hotwork sweet glutinous Semen Maydis special nutritional.
Background technology
In recent years, along with the raising of people's living standard and cooking culture, the diversity of corn variety was also subject to liking of consumers in general, and tropical sweet glutinous Semen Maydis is eaten produce market raw, and supply falls short of demand.The Maize used as fruit or vegetable of China is in the period of developing rapidly at present, and hotwork develops into spring, summer, autumn planting by winter kind planting time, and its development prospect is better.
Yet what hotwork sweet glutinous Semen Maydis fertilising at present was mainly used is readily avaiable fertilizer, also there is no special fertilizer, because torrid areas is long rainy season, rainfall is large, and fertilizer nutrient particularly nitrogenous fertilizer dissolves soon in soil, easily runs off rapidly, the utilization ratio of fertilizer is low, causes the serious wasting of resources, and poor effect.On fertilizing method, still phosphorus, potassium are made base fertilizer, in conjunction with sowing, apply; Nitrogenous fertilizer topdresses.These two aspects are all perplexing Maize Production, and this is the fertile urgent problem of corn.
Release and release control fertilizer is can realize nutrient to discharge the new-type fertilizer of synchronizeing with Crop, can according to the growth demand of crop, control burst size and the release rate of fertilizer nutrient, reaches the efficient object of volume increase.But if it is high separately it to be used in to corn cost, peasant is difficult to be accepted, and is unfavorable for application.
For this reason, we utilize the Nutrient Release that is reacted into membrane envelope urea Controlled Release Fertilizer, simultaneously according to the law of nutritive absorption of corn, the single kind Controlled Release Fertilizer and the part quick-acting fertilizer that difference are discharged to period carry out composite, added the necessary trace element zinc of corn simultaneously, form the synchronous Controlled Release Fertilizer of hotwork sweet glutinous Semen Maydis special nutritional, carried out a large amount of field experiments, obtained good effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides the synchronous Controlled Release Fertilizer of a kind of hotwork sweet glutinous Semen Maydis special nutritional, utilize different release periods to be reacted into the Nutrient Release of membrane envelope Controlled Release Fertilizer, according to the law of nutritive absorption of corn, single kind release and release control fertilizer and the part readily avaiable fertilizer of specific release period are carried out to the composite synchronous Controlled Release Fertilizer of corn special nutritional that obtains simultaneously, can continue the required nutrient of synchronous supply corn, effectively avoiding disposable uses in a large number high nitrogen chemical fertilizer and in earlier stage supplies nitrogen too much, later stage is for the drawback of nitrogen hunger, improved utilization rate of fertilizer, reduce production cost, having improved peasant is benefited, and a large amount of field experiments have been carried out, obtained good effect.
The present invention is achieved by following technical scheme:
The synchronous Controlled Release Fertilizer of hotwork sweet glutinous Semen Maydis special nutritional, is characterized in that, feed composition is by weight: 15～25 parts, nitrogenous fertilizer, 8～12 parts, phosphate fertilizer, 10～20 parts, potash fertilizer, 0.1～0.5 part, zinc sulfate;
The membrane envelope urea that is reacted into that is reacted into membrane envelope urea and discharges for 60～90 days that described nitrogenous fertilizer is discharged by common urea, 30～60 days forms, and its ratio of weight and number is: common urea: what within 30～60 days, discharge is reacted into membrane envelope urea: the membrane envelope urea that is reacted into discharging for 60～90 days is 6～10:4～8:8～16;
The membrane envelope urea that is reacted into discharging for described 30～60 days refers to that fertilizer releasing period is 30～60 days; The membrane envelope urea that is reacted into discharging for described 60～90 days refers to that fertilizer releasing period is 60～90 days;
