Problems solved by technology

Long-term use of chemical fertilizers, pesticides, and herbicides reduces the content of soil organic matter and the number of microorganisms, resulting in the inability of effective absorption and utilization of chemical fertilizers, destruction of the natural habitat of the soil, and outbreaks of pests and weeds
Force farmers to use larger doses of chemical fertilizers, pesticides, and herbicides, resulting in large-scale agricultural non-point source pollution and serious food safety problems

Embodiment 1

[0063] A kind of crop and green manure crop co-cropping the organic planting method of twice a year crops, is about the organic planting method of the crops of two crops a year of co-planting wheat and milk vetch in rotation and cropping with rice, the organic planting method of crops realizes An organic planting method with multiple functions of soil fertilization, food safety production and grass control, which specifically includes the following steps:

[0064] (1), pretreatment of wheat seeds and milk vetch seeds

[0065] Two days before sowing, carry out the microbial mixed seed dressing treatment of wheat seeds and milk vetch seeds respectively:

[0066] ①, seed dressing treatment of milk vetch seeds, the steps are as follows:

[0067] Before planting the milk vetch seeds, mix the milk vetch rhizobium bacterial agent, add carboxymethyl cellulose sodium to fully mix according to the weight ratio of the rhizobia bacterial agent 1%, to obtain the milk vetch rhizobium bacte...

Embodiment 1

[0090] A control experiment was carried out on the land under the same conditions, and the soil organic matter content was 0.8%. Use herbicides to seal the land, use chemical fertilizers as fertilizers, use 11 kg / mu of seed in wheat fields, mechanized seedling raising of rice stubble, mechanical transplanting, and the row-to-plant spacing is the same as in Example 1. Annual production uses 120 catties / mu of urea, 30 catties / mu of superphosphate, and 45 catties / mu of potassium dihydrogen phosphate. The herbicide was applied 4 times.

[0091] Results: The yield of the wheat field was 400 jin, and the average yield of the rice field was 950 jin. In 2015, there were 53 weeds per square meter in the wheat field (before the second spraying), and in 2016, there were 57 weeds in the wheat field (before the second spraying). There was basically no change in the number of weeds compared to the same period in the past two years.

[0092] By comparing Example 1 with Comparative Example...

Embodiment 2

[0094] A kind of crop and green manure crop co-cropping the organic planting method of twice a year crops, is about the organic planting method of the crops of two crops a year of co-planting wheat and milk vetch in rotation and cropping with rice, the organic planting method of crops realizes An organic planting method with multiple functions of soil fertilization, food safety production and grass control, which specifically includes the following steps:

[0095] (1), pretreatment of wheat seeds and milk vetch seeds

[0096] Two days before sowing, carry out the microbial mixed seed dressing treatment of wheat seeds and milk vetch seeds respectively:

[0097] ①, seed dressing treatment of milk vetch seeds, the steps are as follows:

[0098] Before planting the milk vetch seeds, mix the milk vetch rhizobium bacterial agent, add carboxymethyl cellulose sodium to fully mix according to the weight ratio of the rhizobia bacterial agent 1%, to obtain the milk vetch rhizobium bacte...

Abstract

The invention discloses an organic planting method for crops yielding two crops a year by crop and green manure integrated culture, and particularly discloses the organic planting method for crops yielding two crops a year by mixed sowing and integrated culture of wheat and Chinese milk vetch and crop rotation of rice. To be specific, the organic planting method includes pretreatment of wheat seeds and Chinese milk vetch seeds, field management, wheat harvesting, rice seeding culture, rice seeding transplanting, and management in rice growing. By the organic planting method, weeds can be reduced effectively while sufficient fertility is provided on the premise of guaranteeing crop yield, so that usage of chemical fertilizer and herbicide can be decreased or avoided to meet organic crop production standards, and high-quality safe organic agricultural products are produced.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to an organic planting method for two crops a year in which crops and green manure crops are co-cropped. Background technique [0002] Organic farming is a method of growing plants that uses entirely natural ingredients in the growing process – including soil amendments, fertilization and pest control. These foods are also known as health foods because there are few chemical preservatives or other additives. Compared with chemical planting methods, removing weeds and adding fertilizers are the most labor-intensive steps in organic planting, resulting in high production costs of organic products, and the inability to effectively improve production efficiency. [0003] As a kind of important green manure crops, milk vetch, broad bean and fertile radish were widely used in grain-producing regions that produce twice a year in southern my country. However, because the planting of green...
