Formulation of soil quality fertilizer in melon greenhouse
The greenhouse production of green food in the greenhouse requires the soil to be loose and soft, with moderate sand and sticky, organic matter, rich soil and fertilizer, good structure, complete nutrients, sufficient fertilizer, strong fertility, large number of microorganisms, high activity, and acid and alkali. Appropriate, appropriate oxidation and reduction, soil moisture, water supply, strong water retention, good ventilation, suitable temperature and other fertility traits. Therefore, high-quality, high-quality organic fertilizers must be applied frequently to maintain and increase soil fertility.
We use fresh cow dung, chicken dung, wheat bran, etc. as the main raw material for high-quality fertilizers. And in accordance with 4 copies of cow dung, chicken dung 4 parts, wheat bran 2 parts mixed heap compost into compost.
I. Composting conditions
1. Moisture: The moisture content should be 60~75% of the weight of the heap rot material. Wheat bran must be pre-soaked with enough water before it is mixed with cow dung and chicken manure.
2. Ventilation: Since the heap rot in the early stage is mainly a good gas decomposition, the fertilizer heap should not be pressed too tightly, and some vent holes can be set for corn stalks. The late stage of dumping is mainly due to gas decomposition, which can compact the fertilizer heap and cover with a plastic sheet to facilitate the preservation of nutrients and the accumulation of humus.
3, temperature: 55 °C ~ 65 °C high temperature for about a week, prompting high-temperature microorganisms to strongly decompose organic matter, while killing the eggs of pathogens, and then turning piles in time to cool, in order to facilitate the temperature of microbial activity, promote effective nutrient conversion and humus Synthesis.
4, pH: Microorganisms are suitable for neutral to slightly alkaline conditions, organic matter will produce a variety of organic acids and carbonic acid in the process of heap rot, so that the acidity of the compost is enhanced, so the 5% turfgrass ash and a small amount of Potassium calcium fertilizer can adjust the pH.
5. Ratio of carbon to nitrogen: The C/N ratio of the heap rot material, especially the wheat bran, is large. Adding 5% pure NP to the compound fertilizer can reduce the C/N ratio, promote decomposition, and preserve N nutrients and improve composting. The role of quality.
Second, fertilizer effect
Due to the scientific composition of the heap, the organic fertilizer is decomposed, soft and rich in organic matter, and N, P, K, and intermediate and trace elements are sufficient. Both potential nutrients and quick-acting nutrients provide stable and lasting fertilization. The one-time application of base fertilizer for growing melon in the greenhouse not only has good growth potential, but also has strong disease resistance, large fruits, and high sugar content. In the whole process of growth and development of melon, it is not necessary to top-dress fertilizer and pesticides, but only suitable amount of water. water. Labor-saving and time-saving, low cost, good economic returns.
Green Peas, According to the color of their cotyledons, Peas are divided into two types: green skin, green peas, and
green skin yellow peas. Green peas are green-green peas. Peas in northeast China are the most famous. It is one of China's
important food crops. It has a history of 5,000 years of cultivation. Our company can provide two different frozen peas to meet the needs of different people.
The effect and effect of green peas
Daily
green peas can provide catechins and epicatechins as two kinds of
flavonoid antioxidants. When people get older, there will be more and
more free radicals in the body. Free radicals and aging are positively
related. Nutrition in green beans can resist. Free radical-induced diseases, delaying the speed of body aging, as well as anti-inflammatory, spectral antibacterial effects.
Kidneys of green peas
[Appropriate
population] Green peas are suitable for menopausal women, diabetes and
cardiovascular patients, and mental workers and dieters are also very
suitable for eating green Peas. These people can eat green beans to
improve disease and physical condition.
[Contrained
people] People with severe liver disease, peptic ulcer,
arteriosclerosis, kidney disease, gout, low iodine and other diseases
are not to eat green peas, so as not to aggravate the condition.
