Problems solved by technology

However, the cultivation of Yexiangyou hybrid rice is very regional, and the aroma and aroma substances of rice and rice are different in different locations and under different cultivation and management conditions.
The high temperature in the Yangtze River Basin from late July to mid-August is not conducive to the heading and grain filling of Yexiangyou hybrid rice and the formation of rice quality
When the temperature is higher than 35°C, flowering will affect pollination and fertilization, reduce seed setting rate, and increase rice white belly

Embodiment 1

[0042] The test site is located in Pingtai Village, Yong'an Town, Liuyang City in the late season of 2020. The scent-type high-quality hybrid late rice Yexiangyousi seedlings are used as test materials. The anti-lodging cultivation treatment follows the following technical steps of the present invention: seed coating treatment, printing and positioning on June 3, semi-dry seedling raising with root manure layering, machine transplanting of seedlings with a seedling age of 25 days, alternating dry and wet intermittent irrigation, and middle and later stages Two biochemical adjustments, comprehensive prevention and control of diseases, insect pests and weeds, as well as timely harvesting, suitable temperature drying, and low-temperature storage. One-time application of 10 kg of nitrogen fertilizer (N) and phosphorus fertilizer (P) per mu of field 2 o 5 ) 5 kg, potassium fertilizer (K 2 (2) 8 kilograms, 30 kilograms of calcium-silicon-magnesium multivariate compound fertilizers...

Embodiment 2

[0045] The test site is located in the experimental paddy field of Longping Hi-Tech Academy of Seed Industry, Guanshan Town, Ningxiang County in the late season of 2020. The high-quality late hybrid rice Yexiangyou 9 was used as the test material. According to the following technical steps of the above-mentioned present invention: seed coating treatment, printing and positioning on June 10, root fertilizer layered semi-dry seedling raising, machine-transplanted seedlings with a seedling age of 25 days, alternating dry and wet intermittent irrigation, and biochemical regulation twice in the middle and late stages , comprehensive prevention and control of diseases, insect pests and weeds, as well as timely harvesting, suitable temperature drying, and low temperature storage. One-time application of 10 kg of nitrogen fertilizer (N) and phosphorus fertilizer (P) per mu of field 2 o 5 ) 5 kg, potassium fertilizer (K 2 (2) 8 kilograms, 30 kilograms of calcium-silicon-magnesium mul...

Abstract

The invention discloses a cultivation method for enhancing lodging resistance of Yexiangyou series high-quality hybrid rice. The cultivation method comprises the following steps of: processing seed coatings, carrying out printed positioning sowing, carrying out root manure layered semi-dry rice seedling culture, carrying out proper-depth machine rice seedling transplantation, carrying out one-time balanced fertilizer application, carrying out intermittent irrigation, carrying out middle-period and later period two-time biochemical regulation and control, carrying out comprehensive preventing and curing of diseases, insect pests and weeds, carrying out moderate early harvesting, carrying out proper-temperature drying and machine storing and the like. The cultivation method disclosed by the invention clarifies a synergistic effect and an implementation method of the nitrogen, phosphorus and potassium one-time balanced fertilizer application, calcium, silicon and magnesium assorted fertilizer application and the middle-period and later period two-time biochemical regulation and control for controlling the lodging of the Yexiangyou series high-quality hybrid rice, so that the per unit yield of the high-quality hybrid rice is improved, and the lodging resistance capacity is obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of high-quality and high-yield cultivation of crops, in particular to a cultivation method for enhancing the lodging resistance of Yexiangyou series high-quality hybrid rice. Background technique [0002] Yexiangyou series of high-quality hybrid rice, such as Yexiangyousi Miao, Yexiangyou Yousi, Yexiangyou No. 9, Yexiangyou Lizhan, Yexiangyou No. 2, Yexiangyou Haisi, Yexiangyouhang 1573 and other series of varieties, which have the characteristics of suitable growth period, coordinated group and individual development, balanced panicle and grain structure, high and stable yield, and leaves, chaff, rice grains and other organs will emit aroma substances, which can be smelled in the rice fields planted with Yexiangyou Fragrance, strong aroma of cooked rice, welcomed by growers and consumers. However, the cultivation of Yexiangyou hybrid rice is very regional, and the aroma and aroma substances of rice and ric...
