Description

A kind of method for culturing seedlings of pearl rice Oryza sativa L.

Technical field

The present invention relates to agricultural plantation technology field, be specially the method for culturing seedlings of a kind of pearl rice Oryza sativa L..

Background technology

Pearl rice is the one in rice Semen oryzae sativae, because rice grain is full, color and luster is pure white, it is similar to Margarita and gains the name, pearl rice rice matter is glossy, taste is fragrant and sweet, nutritious, rich in proteins, the compositions such as fat, there is effect of nourishing the stomach, the Chinese best pearl rice place of production is northeastward, also the history of plantation pearl rice is had in Ningxia, seedling cultivation of rice is one of Rice Cropping committed step, the quality of seedling will directly affect harvest and the quality of Oryza sativa L., reasonably carry out seedling cultivation of rice and can not only improve yield and the quality of Oryza sativa L., and make in Oryza sativa L. more eutrophy, improve peasant to be benefited.

Summary of the invention

It is an object of the invention to overcome above-mentioned deficiency existing in prior art, it is provided that the method for culturing seedlings of a kind of pearl rice Oryza sativa L.. The present invention, by optimizing the method for culturing seedlings of Oryza sativa L., strengthens the growing way of rice shoot, and then significantly improves the yield of Oryza sativa L..

For achieving the above object, the present invention provides following technical scheme: the method for culturing seedlings of a kind of pearl rice Oryza sativa L., and the nursery step of described pearl rice Oryza sativa L. is as follows:

The first step: the selection in seedbed and process, selection is prone to water, the soil that physical features is higher arranges seedbed, and carry out furrow stalk, the soil in seedbed is carried out refinement also dry in the sun 1-2 days by employing instrument, and by the ratio uniform of 100 grams every square metre, the soil surface after dry in the sun is applied fertilizer, then insecticide is uniformly applied in the upside of fertilizer, and utilize instrument to make fertilizer, insecticide and soil Homogeneous phase mixing, is then watered in seedbed, make seedbed reach till water content is saturated to and do not flow out;

The raw material of fertilizer is: by quality proportioning, takes chicken manure 10-15, pig manure 10-15, cattle manure 10-15, straw 20-25 and Pond Silt 15-20, and mixed fermentation prepares after drying;

Second step: the selection of seed and process, adopt the floating seed selection of saline solution of mass ratio 10%, the flat kind of drift in removing, pull the seed of sedimentation out, soak seed putting into clear water reserviors after clean for seed clean water, the water temperature 20-30 degree of clear water reserviors, seed soaking time is 2-4 days, seed after seed soaking is at the temperature of 28-32 degree and carries out accelerating germination, make seed grow spore, when bud root length to 0.2CM, stop accelerating germination, then by the dry in the sun at normal temperatures of the seed after accelerating germination one day, the seed after dry in the sun is as sowing kind;

3rd step: sowing, is uniformly sprinkling upon the seed after process the soil surface in seedbed, then utilizes tooth harrow instrument that soil is covered in the surface of the seed, and soil cladding thickness is 1-2CM, then carries out overlay film on the surface in seedbed, plays the effect of moisture-heat preservation;

4th step: seedbed management, seedbed after overlay film, temperature under plastic sheeting controls at 25-30 degree, temperature is too high is aerated cooling, when emergence rate reaches 50%, throws off plastic sheeting, uniformly drench in seedbed according to the dilution proportion special fertilizer for seedling culture of mass ratio 1:100 for the first time, every 100 square metres use fertile 500 grams of nursery, it is ensured that seedling all sprouts, and within later every 10 days, waters a sub-band rich water;

5th step: the prevention and control of plant diseases, pest control, notes the withered Seedling of green grass or young crops of seedling, yellow withered Seedling and withered dead Seedling, uses pesticide to be controlled if desired.

Compared with prior art, the invention has the beneficial effects as follows: nursery program of the present invention is simple, and nursery effect is good, utilize fertilizer to carry out fertile ground, that reduces industry chemical fertilizer makes consumption, pollutes little, and it is high that not only yield gathered in the crops by rice, and quality is good, improve market price, improve the income of peasant.
