Problems solved by technology

After the 21st century, due to the transfer of rural labor to cities and the increase in the rigidity of labor costs, some changes have taken place in hybrid rice planting methods, and a variety of cultivation methods for the purpose of reducing labor costs have been adopted, such as plastic tray seedling raising, throwing seedling cultivation, direct seeding, etc. Cultivation, although the labor intensity of these methods has been eased, the problems of high labor, high cost and low benefit have not been completely solved
However, using the current machine-transplanting cultivation method to plant hybrid rice has the disadvantages of large seed quantity and high production cost, and this disadvantage has become a bottleneck restricting the development of hybrid rice

Embodiment 1

[0009] Example 1 In 2014, a 30-mu demonstration of hybrid early rice single-plant close-planting machine-planting was carried out in Yong'an Town, Liuyang City. The variety is a hybrid early rice variety Zhuliangyou 819, coated with prochloraz rice seed coating agent, soaked the coated seeds for 3 days, rinsed, accelerated germination (broken chest) under heat preservation conditions, and used a photoelectric color sorter to remove non-germinated seeds. After sowing the seeds, the germination rate of the seeds reached 98.5%. Soak water and plow the seedling field, and apply granular compound fertilizer with 45% active ingredients (N:P 2 o 5 :K 2 O =15:15:15) 40 kg. After the seedling bed was leveled, 4 rows of plastic seedling trays were placed on each seedling bed. 2 days before sowing, put the seedling ditch mud into the tray, and remove the stones and sundries in the mud during the tray. Sowing on March 28, the seeds that have been germinated are positioned with a se...

Embodiment 2

[0010] Example 2 In 2014, Sanxianhu Town, Nanxian County conducted a 60-mu demonstration of hybrid mid-season rice single-plant close-planting machine-transplanted cultivation. The variety is a hybrid mid-season rice variety Wuyou 308, which is coated with prochloraz rice seed coating agent, soaked for 2 days, rinsed, and accelerated germination (broken chest) under heat preservation conditions, using a photoelectric color sorter to remove non-germinated seeds After the seeds are sown, the germination rate of the seeds reaches 99.3%. Soak water and plow the seedling field, and apply granular compound fertilizer with 45% active ingredients (N:P 2 o 5 :K 2O =15:15:15) 45kg, after the seedling bed is leveled, place 4 rows of plastic seedling trays on each seedling bed. 2 days before sowing, put the seedling ditch mud into the tray, and remove the stones and sundries in the mud during the tray. Sow on May 31st, place the germinated seeds with a seeder to sow single grains ...

Embodiment 4

[0011] Example 4 In 2014, a 100-mu demonstration of hybrid late rice single-plant close-planting machine-planting was carried out in Pailou Township, Anren County. The variety is a hybrid late rice variety Shengtaiyou 9712 (97% germination rate). Coated with prochloraz rice seed coating agent, soaked the coated seeds for 2 days, washed them clean, accelerated germination (broken chest) under heat preservation conditions, and used photoelectric color sorter to remove non-germinated seeds, the germination rate of sown seeds reached 99.5% %, use a printing seeder to sow, according to the long side direction of the seedling tray, there are 34 grains in each row, and the short side direction is 16 grains in each row. The seeds are positioned and single-grained on the reed paper, and the seeds are fixed with starch glue. Soak water and plow the seedling field, and apply granular compound fertilizer with 45% active ingredients (N:P 2 o 5 :K 2 O =15:15:15) 40 kg. After the seedli...

Abstract

The invention relates to a hybrid rice single-parent dense planting machine transplanting cultivation method. Hybrid rice seeds which do not germinate are removed through a photoelectric color sorter, and germination rate of sown seeds is larger than or equal to 98%. A manual seeder or a printing seeder is adopted to position single-grain seeds for seedling raising, a rice transplanter is used for high-density single-parent seedling machine transplanting, transplanting density is 24-25 thousand holes for double cropping rice and is 18-20 thousand holes for single cropping rice, and high-yield management measures are adopted for field management after greening up. By the method, seed cost can be saved, strong seedlings can be cultivated, yield can be increased remarkably, and comprehensive benefit of rice planting can be increased.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a method for machine-transplanting hybrid rice. Background technique [0002] Hybrid rice is a first-generation hybrid with heterosis produced by selecting two rice varieties that have certain differences in genetics and can complement each other in their excellent traits. Due to the obvious effect of increasing the yield of hybrid rice, my country began to promote hybrid rice on a large scale in 1976, and achieved good results. Since the 1990s, the planting area of ​​hybrid rice in my country has accounted for more than 50% of the total rice area in the country. The large-scale planting of hybrid rice has made a significant contribution to solving the problem of food self-sufficiency in my country. From the 1970s to the 1990s, the hybrid rice planting method was mainly artificial seedling cultivation and transplanting, which was labor-intensive, high production cost, an...
