Problems solved by technology

Although vegetable soil or paddy field soil, pond mud, etc. can be used as substrates for machine-transplanted rice, but with the widespread use of machine-transplanted rice seedlings, the amount of vegetable soil, paddy field soil, and pond mud required is large, which cannot meet the requirements and has to be taken away. Vegetable soil or paddy field soil will affect the continued planting of crops in vegetable soil or paddy field

Embodiment 1

[0038] Weigh 78.9 kg of yellow mud, 11.2 kg of refined organic fertilizer, 0.5 kg of urea, 2.4 kg of superphosphate, 0.6 kg of potassium chloride, and 6.4 kg of rice husk ash; ), the water content should be 10-15%; the refined organic fertilizer is a refined organic fertilizer containing more than 30% organic matter; the above raw materials should be weighed as much as possible, that is, the stubble, weeds, Gravel and other pollutants;

[0039] Crush: crush and sieve the yellow mud; the aperture of the sieve is 4-8mm, and generally a sieve with a 5mm aperture is used;

[0040] Mixing: Mix the above raw materials and stir evenly;

[0041] Maturation: Heap the well-stirred materials for 15-40 days (about 20 days in summer and about 40 days in early spring, adjust the heaping time according to the temperature), and get the stuffy heap matrix;

[0042] Disinfection: 6 to 8 days before sowing, take 5 to 6 grams of Dixon, 90 to 110 times the weight of Dixon water (that is, 5 grams...

Embodiment 2-11

[0047] The raw material kind that embodiment 2-11 uses and preparation method are identical with embodiment 1, only the amount of the raw material that adopts is different from embodiment 1; Table 2 below has shown the concrete that embodiment 1-11 uses raw materials and quality;

[0048] Table 2

[0049]

[0050] Adopt the same method as embodiment 1 for the substrate of rice seedling transplanting that each embodiment obtains to make seedling contrast experiment, obtain the statistical data of each embodiment and comparative example as follows (table 3):

[0051] table 3

[0052]

[0053] As can be seen from the above table 3: the substrate of the rice raising machine transplanting seedlings of the various embodiments of the present invention can fully reach the effect of conventionally used vegetable soil, paddy field soil and pond mud mixture seedling raising, and also slightly better than the conventionally used vegetable soil. Soil, paddy field soil and the effec...

Abstract

The invention discloses a matrix for machine-transplanted rice seedlings and a preparation method thereof. The preparation method comprises steps of firstly, preparing the following raw materials: 75.5-82.2 parts of yellow mud, 7.6-14.8 parts of refined organic fertilizer, 0.4-0.7 part of urea, 1.5-3.3 parts of calcium superphosphate, 0.5-0.8 part of potassium chloride and 4.5-8.2 parts of rice hull ash; secondly, smashing the yellow mud, sieving by a sieve with pore diameter of 4-8mm; thirdly, uniformly mixing and stirring the raw materials; fourthly, piling up the uniformly mixed material for 15-40 days so as to obtain the matrix for the machine-transplanted rice seedlings; fifthly, 6-8 days before seeding, spraying dexon solution onto the matrix for the machine-transplanted rice seedlings to disinfect the matrix. The raw materials are abundant and cheap, and the machine-transplanted rice seedlings cultivated by the matrix are strong and have firmly coiled root systems.

Description

technical field [0001] The invention relates to a substrate for growing rice and a preparation method thereof, in particular to a substrate for rice machine transplanting and a preparation method thereof. Background technique [0002] When transplanting rice seedlings by hand, people usually raise seedlings (or seedlings) in rice fields. This seedling raising in paddy field is not suitable for machine transplanting. In order to adapt to machine transplanting, it is necessary to raise seedlings in the seedling tray, first fill the seedling substrate in the seedling tray, because the temperature is low in early spring, rice machine transplanting is generally concentrated in greenhouses. With the rapid expansion of the area of ​​machine-transplanted rice seedlings, a large number of seedling-raising substrates are needed. At present, people often use vegetable soil, paddy field soil, pond mud, etc. as substrates. These substrates can be used as long as they are acid-adjusted a...
