specific Embodiment approach 1

[0015] Specific implementation mode one: the rice leaf age water-saving cultivation method of this implementation mode, carry out according to the following steps:

[0016] 1. Build a standardized seedling field with water sources, drying pools, beds, roads, water diversion and drainage ditches, soil dumps, compost fields and windbreaks; 2. Coat the rice seeds, and then put the seeds into gauze bags for storage Soak the seeds at 11-12°C for 7-10 days, then break the chest at 31-32°C for 7-10 hours, then accelerate the germination at 25-26°C for 5-8 hours, and let them dry for 1-2 days at room temperature, as the seeds to be sown; 3. Soil preparation: After harvesting the seedling fields of the previous year, shallowly plow 12-18 cm, rake and level off, apply 0.15 kg of organic fertilizer, 10 g of urea, 50 g of diammonium phosphate and 25 g of potassium sulfate per square meter. The depth of fertilization is 3-5 cm; 4. Then carry out pot breeding between March 25 and April 1, s...

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment is different from Embodiment 1 in that: the method for leaf miner control in step 6 and step 7 is to spray 30-50 ml / mu of insecticide on leaves. Others are the same as in the first embodiment.

[0020] The insecticide described in this embodiment is the quick kill purchased from Dalian Ruize Company.

specific Embodiment approach 3

[0021] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step 12, 40 g / mu of tricyclazole wettable powder with a volume concentration of 75% is applied during the 10-leaf elongation period of rice. Others are the same as in the first or second embodiment.

Abstract

The invention provides a rice leaf age water-saving cultivation method and relates to a rice cultivation method. The invention mainly solves the problems that the existing rice cultivation method is low in water saving rate and low in yield. The method provided by the invention comprises the following steps of: building a standard rice field; coating rice seeds, soaking the seeds, bursting chest, accelerating germination, and airing buds, wherein the buds are taken as bud seed to be sowed; preparing soil and fertilizing; raising seedlings in pots, earthing, and then covering a mulch; carrying out temperature management; carrying out moisture management in a three-leaf period; transplanting, applying urea in a four-leaf period, controlling leaf miners and irrigating; controlling the leaf miners and irrigating in a five-leaf period; applying urea in a six-leaf period, and irrigating; irrigating in a seven-leaf period; applying urea in an eight-leaf period, and irrigating; irrigating in a nine-leaf period, and storing rainwater after July; applying the urea and potassium sulphate in a 9.5-leaf period, applying tricyclazole wettable powder in a ten-leaf period, and spraying prochloraz missible oil and kasugamycin water agent in a booting stage; and intermittently irrigating in a heading period and a fructicative period, and draining in a yellow ripe initial stage, thus rice leaf age water-saving cultivation is completed. The method provided by the invention is applied to the field of rice cultivation.

Description

technical field [0001] The invention relates to a rice cultivation method. Background technique [0002] Rice leaf age diagnosis technology is based on leaf age tracking, centering on safe heading of rice, using main stem leaf age to express the growth process of rice, based on leaf age tracking investigation, diagnosing, predicting and taking effective measures according to leaf age growth process. It is a planned cultivation mode that accurately promotes and controls the growth of related organs of rice. Rice "leaf age model" cultivation refers to the leaf age model in the growth process of rice, with leaf age as the index and organ-related growth laws as the biological basis of a new system of cultivation theory and technology. This is based on the sensitivity of rice to water and fertilizer requirements at each growth stage and the law of rice water and fertilizer requirements, and on the basis of exerting rice's own adaptability and regulating function, it is a new cul...
