High-yield and High-efficiency Cultivation Techniques of Dryland Plastic Film Covered with Rice Film

First, the advantages of rice plastic film covering dry pipe

There are four outstanding advantages of rice mulch-covered dry-pipe cultivation: First, it is conducive to the adjustment of agricultural structure and grain variety structure. Rice mulch film covering the dry pipe, on the one hand can not be affected by water conditions, expanding the rice planting area, on the other hand can also solve the problem of eating rice in pure autumn dry food areas, improve the food structure in rural areas. The second is to help farmers in mountainous areas increase production and income. In the mountainous areas, the use of plastic film to cover dry-land rice has resulted in a significant increase in production compared with the planting of autumn drought-fed corn, sweet potato, and soybean. The third is to help improve the ability to fight disasters. Rice adopts mulch-covered dry-pipe technology and is neither afraid of drought (the covered plastic film can play a role in impounding water) but also is not afraid of earthworms. It also grows old and healthy, and has strong root system activity, light pests and diseases, enhanced lodging resistance, and overall resilience. improve. The fourth is to help improve the utilization of water resources. Rice mulch-covered dry pipe can save more than 80% of water use than conventional rice cultivation.

II. Fertility characteristics of plastic rice covered by plastic film

1. The plants became shorter and the number of internodes increased. According to the test, after Teyou 559 rice was cultivated on plastic film covered with dry pipe, the height of the plants was 105-110 cm, which was 5 cm lower than that of conventional cultivation; the number of internodes was 6; With an increase of one, the length of the internodes at the base was significantly shortened, showing strong resistance to lodging.

2. The early tillering is fast, and the time for enough seedlings is early rice mulching to cover the dry pipe cultivation. Due to the use of fertilizer beds for dry seedlings, the quality of seedlings is good, the planting and transplanting are light, and the trees are returned to green. The early stage fertilizers are mainly based and the fertilizer utilization rate is high. Covering the film to keep the temperature warm, is conducive to early emergence of rice seedlings, generally sufficient seedling period 3 to 4 days in advance. In the middle and late stages of growth, due to the adoption of an anhydrous layer of moist management, the invalid childbirth dies faster, and the spike rate is slightly lower, and the general spike rate is about 50%.

3. Fertility process is slowed down, and rice mulching is covered by dry tube cultivation in mature stage. Because the soil is in a state of drought for a long time and short-term wet state during rainfall, the growth and development of rice is affected, the birth process is slowed, and the heading period is generally delayed by 4 to 5 times than conventional cultivation. Days, the speed of grouting slowed down, the grouting time extended, and the maturity period was delayed by 7 to 10 days.

4. The number of panicles increased, and the number of grains decreased. The rice mulch covered the dry pipe, and the seedlings in the early stage were fast, enough seedlings were early enough, the population was large at the peak, and the number of panicles increased. According to the test, Teyou 559 has been mulching with dry film cultivation. The number of panicles is generally 180,000 to 200,000 spikes, an increase of 30,000 to 40,000 ears compared to conventional cultivation. Because of the long-term adoption of anhydrous layer dry tubes, ear differentiation is inhibited. The panicle type was significantly reduced, and the total number of grains per panicle was 130 to 140 grains, which was about 40 grains less than that of conventional cultivation.

Third, rice plastic film covering dry cultivation techniques

1. Select a suitable plot to select a dryland area with high water resources, such as mountainous areas, high-lying land, and low-lying areas. As a cultivated land for plastic film mulching, it is not appropriate to choose a land with shallow soil, poor fertility, and heavy alkali.

2. The selection of drought-tolerant varieties should be based on large ear varieties with good drought tolerance, strong tillering ability, moderate growth period (140-150 days), and high yield potential. At present, there are Teyou 559, Shanyou 559 hybrid rice combination and Zhendao 88 rice varieties that are suitable for cultivation under dry conditions.

3. To cultivate dry-breeding and vigorous rice mulching with dry film, it is necessary to cultivate drought-tolerant and strong-adapted crops with strong adaptability, so as to reduce transplanting and planting injury, shorten the time for returning to live trees, and promote sufficient seedlings in the field. Therefore, we should use the dry bed breeding mode to cultivate eucalyptus, cultivate about 35 days of age, seedling height 20-25 cm, and 3-4 larvae of dry grass.

4. Control group starting point According to the test results, the planting density was too low, and the tiller per plant became more than a panicle, which resulted in irregular tidying, long heading period, and a decrease in the number of grains per panicle, and decreased lodging resistance in the later period; If the density is too large, not only the difficulty of filming when transplanting is increased, but also because the group has a high starting point and the middle population is difficult to control, it is also not conducive to high yield. Therefore, it is necessary to have a suitable group starting point in order to facilitate the high yield of multiple spikelets. Teyou 559, Shanyou 559, Zhendao 88 and other large-spike varieties, suitable planting row spacing 33 cm 165 cm, density 10,000 to 120,000 holes per mu, basic seedlings 60,000 to 80,000.

5, scientific coating in addition to rice before transplanting or transplanting, use ultra-thin plastic film to cover the rice field. Plastic film covers rice fields, which can play a role in water storage and conservation, so as to meet the water demand of rice growth and development. Rice mulching with dry film cultivation, more weeds in the field and more complex grasses must be eliminated in a timely manner: weeds can be used to remove commonweed weeds before filming; weeds and other weeds Heavy blocks can be removed with Shapiro.

6. Reasonable fishery and fertilizer production According to local practice, rice film is covered with dry pipe cultivation. Due to the corresponding increase in fertilizer utilization, the amount of nitrogen fertilizer application should be properly controlled. Generally, the amount of pure nitrogen in the mu should be controlled at about 12.5 kg. The basal fertilizer application accounts for 70% to 80% of the total amount of fertilizer, and should be applied early, deep, and full-layer to prevent high-temperature fertilizer damage. In addition, in the basal fertilizer also pay attention to increase silicon fertilizer. The application amount of panicle fertilizer accounts for 20% to 30% of the total amount of fertilizer, with emphasis on the application of preserved fertilizer. In terms of water management, the key is to pour well the live trees for transplanting and the water for flowering twice. If possible, the number of waterings should be increased as much as possible to ensure a higher yield.

Goji berry of Ningqi No.4 is a good variety selected from cannabis leaves and planted in Ningxia, which has characteristics of advanced yield, high yield, high quality and so on. The yield and quality of goji berry of Ningqi No.4 are similar to that of goji berry of Ningqi No.1, however, the ability of resistance toinsects and black fruit disease is stronger than that of goji berry of Ningqi No.1.
