Novel method for manual transplanting matched with seedling raising in sludge through soft porous trays for rice

Abstract

The invention discloses a novel method for manual transplanting matched with seedling raising in sludge through soft porous trays for rice. The method comprises the following steps of 1, selection ofa seedling raising field, wherein the rice field which has convenient drainage, irrigation and transportation conditions and high fertility and contains few weeds is selected; 2, preparation of the seedling raising field, wherein the seedling raising field is subjected to early ploughing and early retting first, rice straw and weeds are removed thoroughly, and the seedling raising field is soakedin water; 3, preparation of seeds and materials, wherein the seeds and materials comprise hybrid rice seeds, conventional rice seeds, disposal porous trays with 353 holes or disposable porous trays with 434 holes, bamboo brooms, square sensing knifes, bailers, fishing line pulling ropes, bamboo poles with the length of 2 m, arched shed bamboo pieces with the length of 2.2 m and cover film; 4, seedtreatment, wherein seeds are soaked two days before seedling raising, and germination acceleration is started one day before seedling raising; 5, a series of seeding work, wherein the work comprisesthe steps of arranging the trays, filling the trays with mud, conducting flattening through sweeping, performing seeding, inserting rice seedlings, inserting the bamboo pieces, using the cover film for covering and arranging ditches; 6, rice field management; 7, manual transplanting of the seedlings. The method has the advantages of being simple in operation, low in requirements for instruments, equipment, technical conditions and the like and convenient to apply.

Description

technical field [0001] The invention relates to the field of rice, in particular to a new method of artificial hand transplanting and transplanting for paddy soft plug mud seedling raising. Background technique [0002] Rice silt floppy disk seedling raising is to use field silt (rot) mud instead of nutrient soil for floppy disk seedling raising. It is a seedling raising technology with simple operation technology. It has mainly become one of the simple seedling raising methods for machine-transplanted seedlings in recent years. [0003] At present, the traditional seedling raising methods of artificial hand transplanting mainly include wet seedling raising, dry seedling raising and two-stage seedling raising methods. Wet seedling raising, also known as semi-dry seedling raising, is a seedling raising method between water seedling raising and dry seedling raising. It is water preparation, water bed, moist sowing, and rooting. Before the seedlings stand, the seedling field is...

Problems solved by technology

Wet seedling raising, also known as semi-dry seedling raising, is a seedling raising method between water seedling raising and dry seedling raising. It is water preparation, water bed, moist sowing, and rooting. Before the seedlings stand, the seedling field is kept moist and ventilated to benefit the root system and take root. After the seedlings are established, according to the water shortage in the seedling field, intermittent irrigation is a seedling raising method based on humidity. This method is easy to manage, but because the seedlings are deeply rooted, the efficiency of pulling out seedlings is low, and the speed of seedling separation is slow when transplanting by hand; dry seedling raising It is a seedling raising method that only keeps the soil moist and does not keep the water layer during the whole seedling raising process

That is to sow rice seeds on fertile, soft, deep, spongy dry land seedbeds, without establishing a water layer, and using appropriate watering to cultivate rice seedlings, but often due to water shortages, the emergence of seedlings is uneven and prone to blight , the root system is developed, the efficiency of pulling out seedlings is low, and the speed of seedling division is slow when transplanting by hand; two-stage seedling raising is a seedling raising method that divides the entire seedling raising process into two stages

The first stage is to cultivate small seedlings with 3 to 4 leaves by means of dense sowing dry seedling raising or wet seedling raising. The second stage is the stage of sending seedlings. In the seedling field, after the seedlings are cultivated into many tillers, they are transplanted to the field. Although there is no need to separate the seedlings when transplanting by hand, this method of raising seedlings is labor-intensive and time-consuming, and the root system of the seedlings is too prosperous, so it is difficult to pull out the seedlings. very inefficient
