2023年12月1日 · The seedling-raising fertilizer used in this experiment is a resin-coated compound fertilizer, which can provide the three kinds of macro-elements for the growth of seedlings. These three nutrients are released slowly after sowing, which ensures that the seedlings can absorb the nutrients immediately when rooting and avoids poisoning the seedlings.

2023年12月23日 · Effects seedling raising methods and sowing rates on machine-transplanted long-age rice seedling

The traditional method of raising seedlings was to sow them in soil in raised beds for better drainage. There is a shift towards using pro-trays because they can be easier to manage and more reliably produce healthy seedlings. However, if farmers are still using the seed bed method of nursery raising, certain good practic-

In southern China, hybrid rice machine transplanting is still mainly based on flat seedling raising technology, which uses the broadcast song method in seedling tray, and does not realize the hybrid rice planting with low seedling number per hill, thus restrictes the promotion of hybrid rice and machine transplantation industrialization in ...

Different ways of raising seedlings Traditional way. In the past, most people used traditional open-field live broadcast methods or sun-borders, improved sun-borders, and solar greenhouses to raise seedlings. Due to the poor equipment and the influence of natural conditions, nursery seedlings are long in age, they have poor quality and uneven size.

Technology of Rice Seedling Raising by Mechanical Transplanting in China Lei Rao, Limei Tang, Baotong Li * College of Agronomy, Jiangxi Agricultural University, Nanchang Jiangxi Received: Sep. 1st, 2019; accepted: Sep. 20th, 2019; published: Sep. 27th, 2019 Abstract

This article compared the advantages and disadvantages of different rice machine transplanting methods and sowing and seedling raising methods in rice production in China, analyzed the problems existing in traditional hybrid rice machine transplanting technology, and innovatively proposed the precision sowing machine transplanting technology ...

【Objective】 The purpose of the study is to ascertain the effect of precise hill-sowing and drill-sowing methods on seedling raising and the characteristics of mechanized transplanting of hybrid rice with a low seed sowing rate below 70 g, and to further break the current technical bottleneck in mechanized transplanting process of hybrid rice.

The seeds of two rice cultivars i.e., Xiangyaxiangzhan and Wufengyou 615 were grown under four different seedling-raising methods i.e., the traditional seedlingraising method (TWSM), the dry seedbed nursery raising method (DSBM), the wet seedbed raising method (WSBM), and the substrate seedbed nursery raising method (SSBM).

This paper briefly reviewed the development of rice seedling raising factories in China, expounded the design and application of intelligent seedling raising factories with the core of stacking seedlings, as well as the precision of hybrid rice planting methods and the realization of intelligent machine transplanting.
