Planting technique

If the area to be planted is more than about 0.1 ha it is worth using a planting machine. 

Never plant strawberries with dry pot halls or roots. To make sure that the plants grow as well as possible, the roots of young plants that are not in pots should not be bent in the soil. If the roots are too long, they can be shortened slightly. 

HOW LONG SHOULD STRAWBERRY PLANTS BE KEPT Strawberries are normally grown for 1 year or for 2 years. When organic production methods are used the 1-year system has the following advantages over the 2-year system  

The 2-year system, on the other hand, is useful in the following cases  

POST-HARVEST CARE OF 2-YEAR CROPS. In dense plantings, every second plant should be removed, or the strawberries should be planted further apart at the outset. After the harvest, the leaves should be mown off with a rotary mower or mulching flail cutter, before the weeds release their seed. If a mulching flail cutter is used, the leaves can be left lying on the ground, otherwise they should be removed.

A comprehensive program that includes predictive maintenance techniques to monitor and analyze critical machines, equipment, and systems in a typical plant. Techniques include vibration analysis, ultrasonics, thermography, tribology, process monitoring, visual inspection, and other non-destructive analysis methods. 

A quite different approach to the study of plant responses to stress has been explored by those ecologists who have followed the example of Harper (1977) in applying to plants techniques originally deployed in investigations of animal populations. Here the methodology has been demographic and the resulting data have allowed responses to stress to be analysed in terms of fluctuations in the rates of mortality and recruitment of either plant populations or plant parts (e.g. leaves, inflorescences).

While the development of flue gas clean-up processes has been progressing for many years, a satisfactory process is not yet available. Lime/limestone wet flue gas desulfurization (FGD) scrubber is the most widely used process in the utility industry at present, owing to the fact that it is the most technically developed and generally the most economically attractive. In spite of this, it is expensive and accounts for about 25-35% of the capital and operating costs of a power plant. Techniques for the post combustion control of nitrogen oxides emissions have not been developed as extensively as those for control of sulfur dioxide emissions. Several approaches have been proposed. Among these, ammonia-based selective catalytic reduction (SCR) has received the most attention. But, SCR may not be suitable for U.S. coal-fired power plants because of reliability concerns and other unresolved technical issues (1). These include uncertain catalyst life, water disposal requirements, and the effects of ammonia by-products on plant components downstream from the reactor. The sensitivity of SCR processes to the cost of NH3 is also the subject of some concern.

Other Nuclei. - 6.2.1 Application to Materials and Plants. Techniques of C-NMR imaging and its apphcations to plants and elastomer blend systems were reviewed. " In this review, the authors focused on the imaging of C nuclei as a means to deal with the spatial distribution of molecules of interest other than water.

The idea of agitating a batch of resin with solution in a beaker to cause reaction is well known for ion-exchange laboratoty experiments and is used to study the kinetics of ion-exchange reactions. The use of this concept as a plant technique is limited by the following factors ... 

Reverse osmosis is used for desalination of seawater, treatment of recycle water in chemical plants and separation of industrial wastes. More recently the technique has been applied to concentration and dehydrogenation of food products such as milk and fruit juices. See ultrafiltralion. 

However, it is expected that this situation will change, since a number of novel "non-invasive NDT techniques are now becoming available. With some of these techniques, the time required for a shutdown can be reduced. Other techniques make it possible to perform inspections whilst the installation is in full service. It is obvious that the availability of such techniques could support the knowledge already available on operational parameters and degradation mechanisms, in order to base shutdown intervals on actual plant condition. 

Plutonium (Pu) is an artificial element of atomic number 94 that has its main radioactive isotopes at 2 °Pu and Pu. The major sources of this element arise from the manufacture and detonation of nuclear weapons and from nuclear reactors. The fallout from detonations and discharges of nuclear waste are the major sources of plutonium contamination of the environment, where it is trapped in soils and plant or animal life. Since the contamination levels are generally very low, a sensitive technique is needed to estimate its concentration. However, not only the total amount can be estimated. Measurement of the isotope ratio provides information about its likely... 

Until separation techniques such as chromatography (28,29) and counter-current extraction had advanced sufficientiy to be of widespread use, the principal alkaloids were isolated from plant extracts and the minor constituents were either discarded or remained uninvestigated. With the advent of, first, column, then preparative thin layer, and now high pressure Hquid chromatography, even very low concentrations of materials of physiological significance can be obtained in commercial quantities. The alkaloid leurocristine (vincristine, 22, R = CHO), one of the more than 90 alkaloids found in Catharanthus roseus G. Don, from which it is isolated and then used in chemotherapy, occurs in concentrations of about 2 mg/100 kg of plant material. 

This article is intended to provide a useful first understanding of flow phenomena and techniques and to provide an entry to more precise and detailed methods where these are required. Although the main concern is the proper design and operation of plant equipment, the importance of preservation of the environment is recognized. Thus data from the fields of meteorology and oceanography are occasionally needed by the technologist (see also Flowl asurel nt Fluidization). 

A subsidiary of lEC and Toshiba Corp. called ONSI Corp. was formed for the commercial development, production, and marketing of packaged PAEC power plants of up to 1-MW capacities. ONSI is commercially manufacturing 200-kW PAEC systems for use in a PC25 power plant. The power plants are manufactured in a highly automated faciHty, using robotic techniques to assemble the repeating electrode, bipolar separator, etc, units into the fuel cell stack.
