In the context of current consumption upgrading, various economic crops have achieved good returns, such as the prices of economic crops such as tea, tobacco, fruits, etc. are rising; especially, in the context of pursuing an idea of organic crops, while the demand for economic crops has increased, the pursuit of quality has also increased.
is constantly strengthened by the concept of "organic" and continues to the process of planting crops. We should eliminate the use of chemical fertilizers as much as possible. In order to maintain soil fertility, we have the concept of organic fertilizers.
Organic fertilizer
Organic green manure on the market is generally made of animal feces or plant decay, but the output is far from the demand for use, so the price is high and the quantity is small.
Here, the editor of Seed Bud will share with you the secret weapon for increasing production of economic crops - green fertilizer planting technology
Green manure, that is, green plant fertilizer. Green manure planting can increase the organic matter content of soil, improve the soil's granular structure and physical and chemical properties, improve the soil's own ability to regulate water, fertilizer, gas and heat, form a good crop growth environment, cultivate ground fertilization, and lay the foundation for sustainable development. Green manure planting mainly uses autumn and winter fields to rotate and intercrop green manure and grain crops. While harvesting grass normally for livestock breeding, the soil fertility is maintained and improved by turning green manure back to the field;
plant green manure, and green manure and grain rotation or intercrop, that is, fertilizing ground fertility, increasing yield, protecting the environment, increasing production and efficiency, which is worthy of management and promotion~

green manure return to the field
green manure return to the field planting technology is generally divided into the following Several types:
1. Rotating green manure return technology
Rotating green manure return refers to the planting method of rotating different crops or compound combinations on the same field in sequence between seasons and years. Generally, rotation green manure is mainly legume plant , mainly alfalfa, large-leaf clover, arrow tongue pea, broad beans, field green, etc....
Rotating green manure Because of the long growth time, the sowing methods can be spreading, strip sowing, machine sowing, etc. The entire growth period can be harvested 2 to 3 times, and the biological output of different green manure varieties is also different. Generally, 1,500 to 2,000 kilograms of hay are harvested throughout the year. Take forage as an example. 20 cm should be left for each harvest to ensure the growth of the next crop.

It is better to make green manure return to the fields during the inter-pressing process to ensure that the branches and leaves are not exposed. When turning the branches and leaves are lush, the steps of suppressing first, then chopping, and then turning the fields can be adopted. After turning and pressing, watering should be done in time, and the application of urea and straw decomposition agent should be combined to promote the decomposition of green manure.

3. Professional Vagina planting technology
Green fertilizer Vagina professionally used in the field green fertilizer planting, and the main types are light-leaf Vagina, hairy Vagina, orchid Vagina, etc.
Hairy Vagina is mainly distributed in North China, Northwest, Southwest and other regions as well as in northern Jiangsu and northern Anhui. It is generally used for rice field replanting or wheat field interplanting.
Professional green manure-haired vulgaris
Orchid vulgaris is mainly distributed in southern provinces, especially Hubei, Sichuan, Yunnan, Guizhou and other provinces. It is generally used for autumn sowing of rice fields or planting between farms.
Seed treatment should be carried out before sowing, so that the seeds are sown after fermentation can increase the germination rate. At the same time, use molybdenum fertilizer and rhizoblast bacteria to mix seeds, and apply phosphate fertilizer to promote early formation of rhizoblasts. As a green manure for wintering, the sowing period of the sweet potato should be between August and October. The autumn sowing in North China and Northwest China is in August, the Huaihe River is in August to September, and the Jiangnan and Southwest China are in September to October.
Vaginal seeds
Crops sowing mainly after harvesting, and those with symbiotic periods with the previous work are spread, and interseeding is carried out or acupoint sowing. The space for sowing is 25 to 30 cm. It is better to keep farming to a thinner one, 40 to 45 cm. For green manure and green pressing, the sowing volume per 667 square meters is 2 to 5 kilograms, up to 6 kilograms, the amount of spreading is 4 to 5 kilograms per 667 square meters, and the amount of hole sowing is 2 to 4 kilograms per 667 square meters; the sowing volume is 1.5 to 2.5 kilograms.
