Abstract
The invention relates to a water retention compound nitrogen fertilizer which comprises the following components in parts by weight: 20-38 parts of ammonium chloride, 12-17 parts of ammonium nitrate, 10-30 parts of bentonite and 10-15 parts of water-retaining agent, wherein the water-retaining agent is a starch-grafted acrylate copolymerized cross-linking agent. The nitrogen fertilizer further comprises 0.1-0.2 part of rooting agent and 0.1-0.3 part of swelling agent. By using the water retention compound nitrogen fertilizer, the growth and development of crops can be promoted effectively, the fruit quality can be improved, the cold resistance and drought resistance of plants are improved, the contents of sugar and vitamin C in fruits are increased, the yield of crops can be increased effectively, the quality of plants is well improved, and growth promoting and accelerating effects are achieved. Meanwhile, the water retention compound nitrogen fertilizer has great advantages on the aspects of improving soil environment, increasing the fertilizer making capacity and promoting the microbial metabolism of soil.
Description
Technical field
The present invention relates to a kind of chemical fertilizer, relate in particular to a kind of water conservation composite nitrogen fertilizer.
Background technology
Nitrogen is one of essential nutrient of plant-growth, in the time that nitrogen is sufficient, plant can be synthesized more protein, promotes division and the growth of cell, once and crop nitrogen stress, often show as poor growth, plant is short and small, and blade is thin and little, the jaundice of leaf look minus green, gramineous crop divides evil few, and fringe is short and small, hollow kernels.But existing nitrogenous fertilizer, its nutrition is comparatively single, although can Promoting plant growth, cannot meet the demands for the drought resisting of crop, aspect resistant to lodging, and use for a long time consequences such as easily causing soil compaction, edatope deterioration.Generally adopt at present the slowly-releasing composition of humic acids as fertilizer sources, extend the time of fertilizer to crop alimentary supply, the a large amount of losses that reduce fertilizer play an important role, and humic acids can promote the dietetic alimentation of crop, but after Crop nutrition, it is distributed in and has where really different plants to determine.Also do not solve at present the orientation transportation of nutritive substance in plant materials and the effective ways of accumulation problem.Plant is by the growth of the nutrition absorbing or supply branches and leaves, or the growth of supply fruit, or the growth of supply root, although the nutrition that therefore fertilizer provides is sometimes absorbed by crops, does not obtain expected effect, crop growing state is gratifying, but may not output improve, quality is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of herbicide for paddy field.
For solving the problems of the technologies described above, water conservation composite nitrogen fertilizer of the present invention, it contains following component, ammonium chloride 20-38 part, ammonium nitrate 12-17 part, wilkinite 10-30 part, water-holding agent 10-15 part.
Described water-holding agent is starch grafted acrylate crosslinking copolymerization thing.
Described nitrogenous fertilizer also comprises root-growing agent 0.1-0.2 part, swelling agent 0.1-0.3 part.
Water conservation composite nitrogen fertilizer of the present invention not only can effectively promote crop growth, and can improve fruit quality, enhancing plant is cold-resistant, drought-resistant ability, improve sugar and the ascorbic content of fruit, and can effectively improve crop yield, the quality of plant self is had to good improvement, can produce growth encourage, the long effect of speed, improving edatope, fertile ability is made in strengthening simultaneously, promotes soil microorganisms metabolism conveniently to have stronger advantage.
