Description

Rice and wheat continuous cropping double-seed soaking germination accelerating and robbing annual high yield technology system Technical Field The invention relates to the technical field of agricultural planting, in particular to a double-season seed soaking germination accelerating and time robbing sowing technology under a rice and wheat annual rotation system, and especially relates to a technical system for realizing annual high yield through time coordination and physiological regulation of pretreatment of seeds in two seasons. Background In the middle and downstream rice and wheat double cropping zone of the Yangtze river, the traditional production mode has the following structural contradiction: (1) Season linking time tension Rice and wheat rotation has the contradiction of overlapping seasons of harvesting and sowing. When the former crop is mature, the latter crop needs to be sown immediately, but the seed preparation needs time, which leads to delay of farming time. In the traditional mode, the effective physiological activity days of the whole year are only about 350 days, and the idle clearance is wasted for about 15 days, so that the time efficiency is insufficient. (2) Unstable seedling emergence quality Under the direct seeding mode of dry seeds, the seed swelling process is limited by soil moisture content, the seedling emergence time is trailing for 7 to 10 days, and the uniformity variation coefficient is as high as 25%. Although the conventional germination accelerating method can shorten the emergence time, the seeding window is only 3 days, the buds are too long when the weather is delayed, the mechanical damage is serious, and a systematic time coordination mechanism is lacked. (3) Double-season technique cleavage The prior art is mostly aimed at single Ji Zuowu, and lacks the collaborative design of double seasons of rice and wheat. The seed soaking and germination accelerating parameters, time window and mechanical adaptation of the rice and the wheat are independent, and a year-round integrated technical system is not formed. (4) Empirical seed treatment The existing seed soaking and germination accelerating method is dependent on farmer experience, lacks standardized industrial facilities and intelligent decision support, has poor quality, and is difficult to popularize in large scale. Compared with the prior art, the system has the following characteristics: (1) Comparison with the technique of Zhu Xin et al Zhu Xin, et al, in 2020, propose a technique for accelerating germination of late-sowing wheat seeds by soaking seeds (advantages and technical keys of accelerating germination of late-sowing wheat seeds by soaking seeds) and the core comprises soaking seeds in clear water, accelerating germination at proper temperature, airing and sowing, and the seeds after accelerating germination are definitely required to be sowed within 3 days. The technology has the following limitations that a sowing window is only 3 days, the farm time fault tolerance is poor, the technology does not relate to the cooperative design of rice and wheat in double seasons, the technology lacks industrial facilities and an intelligent decision system, and the technology does not have a physical activating means to promote the vigor of seeds. (2) Contrast to the technique of stress-resistant seed treatment in coastal saline-alkali soil The application and a complementary patent combination under the same technical conception are formed by a comparison application of an innovative integration method for stress-resistant seed treatment and functional seed product of wheat late-sowed in coastal saline-alkali soil, and the specific coordination relationship is as follows: The regional complementation is that the comparative application aims at the special adversity of the coastal saline-alkali soil, the salt content of the cultivation layer is 0.2-0.35%, and the cultivation layer belongs to the salt stress environment, and the cultivation method aims at Jiang Huaidao wheat double-maturing area standard farmland, and belongs to the conventional agricultural production environment. The two applications cover different application scenes to form regional complementation. The application has the advantages of complementation of functions, focusing and salt resistance functions, construction of stress resistance barriers through triple coating of a chemical protection unit, a physical barrier unit and a physiological induction unit, coordination of focusing time efficiency and year round, and improvement of production efficiency through a physical activation mode and an industrial system. The two applications complement each other in functional orientation. The parameters are complementary, the water content range of the application is 28-30% compared with the application, the temperature is controlled to 8-12 ℃ in a precise narrow range, the water content range is 26-32% in a low-temperature preservation range,
