A. Green manure
Green manure is a cultivated plant used primarily as a fertilizer. However, it is applied off-site with fresh plant bodies turned in situ, or composted and composted.
B. Types of green manure
Green manure is mostly legumes, but also grasses and cruciferous plants.
C. Planting green manure to improve organic matter
However, due to the increasing replanting index and yields, soil nutrients are released and utilized quickly but are difficult to replenish in time. Therefore, planting green fat can return organic matter and minerals to the soil more quickly.
D. Leguminous green manure
Thus balanced supplementation of leguminous green fat plants with the ability to fix free nitrogen in the air.
E. Use of biological nitrogen fixation
However, it can use biological nitrogen fixation to increase soil nitrogen and has a well-developed root system, so it can absorb and use nutrients that are not easily available to general crops below the soil tillage.
However, it is concentrated in the ground, and after the green fat is tilled and decomposed, it provides more fresh organic matter and calcium and other nutrients to the soil. Therefore, it accelerates soil maturation and improves low yielding fields with strong penetration and agglomeration of root system.
G. Good physical and chemical properties of soil
However, it is conducive to the growth of crops Our city has a semi-arid and semi-humid monsoon climate.
H. Area planting green manure
However, six counties in Weibei have dry winters and springs, with much sand and wind, and green fat is planted during the recreational season. Therefore, it can reduce soil wind and water erosion, maintain soil and water to provide livestock forage section in the orchard planting green fat crops. Most importantly, it can make full use of light energy and improve the small environment.
I. Benefits of planting green manure
However, it regulates local temperature and soil moisture, thus suppressing weed growth and improving soil fertility.
J. Guanzhong Irrigation District
The cropping system is biannual or biannual, and the ground power is consumed, and continuous crop is easy to cause pests and diseases to aggravate and affect the yield. Green fat and crop intercropping or reverse crop, can not only cultivate fertility. It can also reduce the harm caused by continuous crop.
K. Green manure suitable for local cultivation
1. Green manure of hairy leaves
Hairy leaves are often interplanted between the rows of get crops and forest fruit planting. It has strong drought and cold resistance in the garden, is not strict on soil requirements, and has poor salvage resistance. It grows best in well-drained loamy soil.
2. Pea green manure
It is an important food, vegetable and fertilizer crop. It is mainly used as a pre-crop for cotton. The stalks are turned and pressed for green fat with high water and fertilizer requirements and are not tolerant of flooding.
3. Mung bean green manure
It is an excellent grain and fertilizer crop, but also an important legume cash crop. Mostly planted in spring and summer, interplanted or wheat field replanting. Strong moisture tolerance, can grow well in the ground
4. Broad bean green fertilizer
Is also an excellent grain, vegetables, fertilizer and crops. Mainly in the fall or early spring sowing. Mostly with other crops asked to plant. Picking green pods for vegetables or harvest seeds for consumption, stalks and residues back to the field for fertilizer. High requirements for water and fertilizer. Does not tolerate stains and drought.
5. Grass green manure
It can also planted between the rows of economic trees or on hilly areas to maintain water and soil. Grasses are drought-resistant, cold-resistant and barren, and have high nutrient content. Not only is it an excellent green fat, but also an important forage for use. Forage to processed and modulated into hay, or silage after suitable for livestock consumption.
6. Yang hemp green fertilizer
Mostly used as an inter-set or filling leisure. Is also an important summer green fat. Drought tolerance is strong, but not stain tolerance. Planted on well-drained fields is good
7. Sativa green manure
Sativa is a kind of green fertilizer for both forage and soil conservation. It can planted in crop rotation with grain or between forest and fruit rows and on slopes. It is highly adaptable, resistant to cold, drought and sand. Tolerant to infertile, but not to waterlogging. It is an excellent green fat for both fertilization and feeding in semi-arid areas.
8. Chanticleer green fertilizer
Vanilla plant and seeds are edible, and are good seasoning. Mostly replanted in summer and autumn wheat fields, but also in interplanting with other crops. Prefer cool climate, avoid high temperature intolerant of cold grows vigorously in water and fertilizer conditions and on well-drained soil. Does not tolerate waterlogging and salinity.
9. Pea green manure
Wild peas are mostly replanted or interplanted in wheat and cotton fields. It can also planted in fruit and mulberry gardens for wider adaptability. Not tolerant of moisture, not saline. However, it is drought tolerant and likes a cool, moist climate. The seeds contain hydrocyanic acid, which can be toxic to humans and animals in excess. It needs to decontaminated after steaming or soaking. The seeds have high starch content and can used to extract starch instead of broad beans and peas. It is an important raw material for high quality vermicelli
Prefer moist warm climate more drought tolerant, cold hardy suitable for well-drained. Calcium-rich clay soil growth growth cycle is generally 2-6 years. In warm conditions often shortened to biennial or annual. Clover provides habitat for beneficial insects such as ladybugs, big-eyed bugs, soft-bodied flower beetles and other predators.
L. Other green manures
In addition, legume crops such as soybeans, tank beans and peanuts The stems and leaves can also turned into the soil as green manure while harvesting the seeds.
M. Precautions for planting green manure
① During the growing period of green fat, we should apply appropriate amount of N,P,K fertilizer. In particular, we should increase the application of phosphorus fertilizer to alleviate the conflict between green fat crops and fruit trees for fertilizer.
② Select dwarf or semi-creeping green fat crops.
③Sow perennial green fat crops. Generally 4-5 years need to plowed and reseeded.
④When applying green fat, water the green fat in time after it is pressed green to accelerate its decay and decomposition.
⑤ Deep-rooted legumes and trees compete for water are usually not planted in orchards
⑥Legume green fat can provide important nitrogen to fruit trees. But too much nitrogen will reduce fruit yield so orchard planting green fat to pasture is better
(1) Green manure fertilization
However, it is better to turn in the soil at the time of full flowering. Therefore, this is the time when the green fat accumulates the most organic matter and the best results.
(2) Newly introduced green manure varieties
To do a trial test before planting a large area to avoid blind planting caused by ecological disasters and other adverse consequences
