Problems solved by technology

There are many kinds of green manures. Milk vetch is the main traditional green manure in my country. Its mechanism is that the rhizobia symbiotic with leguminous plants can fix nitrogen from the air. Then there is the bottleneck of high yield, so the value of milk vetch as an organic nitrogen stock is reduced. In addition to economic factors, the area for farmers to plant milk vetch as green manure is getting smaller and smaller, and a large number of idle fields in winter appear in many areas of our country

Embodiment 1

[0029] From the autumn of 2005 to the summer of 2006, the planting method of returning rape flower pods to the field as green manure to increase rice yield was carried out in Caixingquanhu, Huayuan Village, Hecun Town, Jiangshan Town, Zhejiang Province. The field area is 1.23 mu.

[0030] The specific steps are as follows: On October 25, 2005, the paddy field was ditched to make a furrow, the furrow width was 2.5m, the furrow width was 0.2m, and the paddy field was no-tillage; on October 26, the rapeseed was broadcast live, and the selected variety was the cabbage-type hybrid variety Zheyou 18, mu The amount of seed used is 0.25kg. When sowing, mix the rapeseed with 1.5kg of fine mud and spread it; do not apply herbicides before sowing rapeseed, only use 12.5% ​​grass at the 3-leaf stage to cover 70ml per mu, add 50kg of water to spray ; At the 3-leaf stage and the bolting stage, the fertilizer was topdressed once, and the amount of fertilizer applied per mu was 2 kg of urea an...

Embodiment 2

[0033] From 2004 to 2008, the China Rice Research Institute (Fuyang, Zhejiang) farm conducted a positioning test of different rice field planting methods, and set up 3 treatments: the planting method of returning rape pods to the field as green manure to increase rice yield (T1), milk vetch The planting method (T2) of returning to the field to do green manure and then stubble rice during the full flowering period, and the method (T3) of planting rice in winter and spring in the paddy field, each treatment area is 2 mu.

[0034] The specific operation of the planting method (T1) of returning rapeseed pods to the field as green manure to increase rice yield is as follows: 1) From 2004 to 2007, rapeseed was broadcast live on October 20 every year, and the selected variety was the cabbage hybrid variety Zheshuang 72, mu The amount of seed used is 0.3kg. When sowing, mix the rapeseed with 1.5kg of fine mud and spread it; 2) No herbicides are applied before sowing rapeseed, and only ...

Abstract

The invention discloses a planting method for increasing rice yield by returning rape as green manure during the flowering stage. The method comprises the steps of: ditching a rice field as furrows in late October, and directly planting rape seeds without tillage; spraying phytocide once only during the (3-4)-leaf stage in growth of the rape, and further fertilizing the rape once during the (3-4)-leaf stage and the peduncle-growing period respectively; cutting off the rape during the flowering stage, and mechanically turning over the soil to restore the field after irrigating the soil; planting the stubbled rice in ridge furrows, controlling water irrigation during the growth period, retaining the shallow water layers during the seedling establishment stage, the disease and pest prevention and treatment stage and the head sprouting and flowering stage, keeping the ditch to have water while keeping the furrows to have no water on surface during a period except the periods above, wherein the fertilizing amount of the rice is reduced by 15%. The planting method for increasing rice yield by returning rape as green manure during the flowering stage combines rice production with biologic cultivation and fertilization, not only reduces the fertilizing amount of the rice but also increases the yield of the rice and improves the physical properties of the soil of the rice field, so theplanting method is characterized by saving labor and cost and achieving high yield and high efficiency.

Description

technical field [0001] The invention relates to a cultivation method for crops, in particular to a cultivation method for returning rapeseed to the field at the flower pod stage as green manure to increase rice yield. Background technique [0002] At present, rice production has problems such as a single paddy field planting system, a large reduction in the amount of organic fertilizers, and a large amount of chemical fertilizers. The soil physical and chemical properties deteriorated, the secondary potential and compaction of paddy fields became more and more serious, the sustainable production capacity of paddy soil was threatened, and the per unit area yield of rice remained stagnant. [0003] Planting green manure can improve the soil structure of paddy fields and increase soil fertility. There are many kinds of green manures. Milk vetch is the main traditional green manure in my country. Its mechanism is that rhizobia symbiotic with leguminous plants can fix nitrogen ...
