Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The medicament or the apparatus used is not indicated by the manufacturer, and is a conventional product which can be obtained by commercial purchase.

The planting method of foliage rice of the embodiment of the present invention is specifically described below.

The method comprises the steps of selecting the plump seeds with high germination rate, sunning the seeds for 2 days to sterilize and improve the seed activity, soaking the seeds by adopting a conventional rice seed soaking agent, killing harmful germs on the surface of the seed coat to prevent rice seed-borne diseases, carrying out proper germination acceleration on the soaked seeds, and during germination acceleration, controlling the temperature of a seed production stack to be between 32 and 35 ℃, so that the method can prevent over-high temperature germination, can ensure that the seeds germinate relatively quickly and neatly, selects a land with fine soil and flat land after plowing to serve as a seedling field, and has uniform soil fertility.

The seedling is raised by adopting a wet seedling raising mode, a seedling tray seedling raising mode or a dry seedling raising mode, and the seedling tray seedling raising mode has the advantages of uniform seeding, suitability for seedling transportation, small root system damage during seedling raising, suitability for shallow planting without falling seedlings during transplanting and contribution to low-node tillering, so that the seedling tray seedling raising mode is preferably adopted, the purposes of preventing low-temperature cold tide and bird pecking and keeping warm and moisture are achieved, blue film covering is adopted in the early stage of seedling raising, an arch film is adopted as a covering mode, and the purposes of preventing the seedlings from bud burning and seedling burning caused by the contact of the seedlings and the films are achieved. The seeding is fine, uniform and thin, and each hole is seeded with no more than 2 grains, preferably 1 grain, so as to ensure the growth of the seedlings to be consistent and promote the early tillering of the seedlings.

Transplanting when the seedlings grow 5-6 leaves, and transplanting to a field, a pot, a water pool or a landscape place. The soil of the transplanting land needs to be deep, enough base fertilizer is applied, the planting needs to be shallow and stable, the seedlings need to be planted correctly, the planting depth is suitable for the plants to stand and not fall, and the early rooting and the early quick growing of low-node tillering are facilitated. Compared with the local common rice, the transplanting density is slightly thinner, so that the multiple tillering is facilitated.

After the flowers are raised, the rice ears are cut from the positions of the sword leaf pillows, and the purpose of cutting the rice ears is to cut off the delivery of photosynthetic nutrients to the ear parts, so that roots, stems and leaves can obtain more nutrients, and the generation of new tillers at the stem base parts is facilitated. The tassel is cut from the sword leaf pillow to protect the leaves from being damaged, the sword leaf, the inverted second leaf and the inverted third leaf are fully utilized to produce photosynthetic products, and the cut is not exposed obviously, so that the appreciation is not influenced. The ear shearing time is put after blooming because the newly drawn rice ears are tender and tender, the rice ears in the blooming period are charming and are a period with good ornamental value, some leaf-viewing rice ears have bright colors, the ear shearing time can be postponed to the middle stage of grouting, when at least 1/3 tillers grow out not less than 1 leaf at the lower part, the stems with the sheared ears are sheared at the position 3-5cm away from the soil surface at the base part, the aim is to promote the low-node buds to germinate and generate tillers, the stubbles are low, and the cut openings can be covered by the newly grown tillers without affecting the ornamental value. When the stem is cut, the tillering seedlings are not damaged.

The ears are firstly cut, then the stems are cut, a transition time is arranged in the middle, so that the rice plants are ensured to have leaves for viewing all the time, the condition that the direct stem cutting can cause the loss of the viewing performance within a certain time is avoided, and the ears of the rice are cut off from the positions of the sword leaf pillows after the second batch of ears are drawn out. When the stem shearing time is that the leaves on the stem turn yellow or have the aging signs, the stem shearing time is postponed until the leaves on the stem turn yellow or have the aging signs, because the temperature gradually drops in autumn, tillering generation and growth become slow, the stem shearing can make the whole rice plant thin and reduce the ornamental value, but when the root of the leaf-watching rice has more tillers (more than or equal to 10 tillers/holes), the temperature at night is more than or equal to 15 ℃, the average temperature in day is more than or equal to 20 ℃, the stem shearing can be carried out when the lower tillers grow 2-3 leaves.

In the planting process, the foliage-watching rice is further fertilized in different growth periods, 10 per mu of decomposed liquid dung is sprayed with clear water in a two-leaf one-core period of the seedling, the mixed fertilizer of the decomposed liquid dung and the urea is applied once every 7 days, the dosage of each time is determined according to the growth vigor of the seedling, a shallow water layer is kept in the field within 1-2 days after the topdressing so that the fertilizer can be uniformly diffused, and 20kg per mu of urea is sprayed in 5 days before the transplanting; base fertilizer, which is to uniformly spread 2000-plus-one (mixed, composted and composted crop straws and animal manure) 1500-plus-one (2000 kg/mu) manure on the field surface before plowing, irrigate and foam the field after plowing and harrowing, then uniformly mix the manure on the cultivation layer by combining the plowing and harrowing, slowly release the nutrients of the manure, continuously provide nutrition for rice plants in the later stage of rice growth, and uniformly apply 30-40 kg/mu of NPK ternary compound fertilizer before harrowing for the last time; topdressing, namely topdressing by using urea 10-15 kg/mu according to the seedling condition 10-15 days after transplanting and turning green; properly applying 5-10 kg/mu of urea according to the growth vigor of the field plants in the middle and later tillering stages so that small tillered seedlings can obtain sufficient nutrients and do not die; in the early stage of booting, additionally applying a proper amount of water-soluble compound fertilizer 10-20 kg/mu according to the growth vigor of the field to supplement nitrogen, phosphorus and potassium nutrients for rice plants so as to prevent the rice plants from being lack of elements; topdressing is carried out after scion cutting, 10-20 kg/mu of urea is topdressed according to the seedling condition per mu after the first scion cutting, the growth of dormant buds at the stem base is promoted, the growth of rice leaves is kept, the service life of old roots is prolonged, and then proper amount of urea is topdressed according to the seedling condition growth, so that the good growth condition of rice plant leaves is kept.

The water slurry management comprises shallow water transplanting, and a water layer of about 3cm is kept after green turning, so that the soil temperature and the water temperature are improved, and tillering is promoted; the leaf area in the field is large and the evaporation capacity is large until the ear sprouting in the later tillering stage, and a water layer of 3-5cm is kept to meet the requirement of the growth of rice plants; after cutting, a water layer of about 3cm was maintained. The water can not be cut off in the whole growth process of the leaf-watching rice, the generation of ineffective tillering is not controlled, the more tillering, the more flourishing the rice plant, and the better the appreciation.
