Grafting Method - Bridge Grafting and T-Grafting

Bridge Grafting and T-Grafting

Bridge Grafting

It is practiced to save valuable trees with diseased or damaged trunks. To prepare the tree trunk for bridge grafting, the damaged part is trimmed back to healthy tissue by removing dead or torn bark from the affected parts.
 Bridge grafting is best performed during early spring when the bark can be lifted easily. Scions of sufficient length to bridge over the damaged area are taken. One long slanting cut is made at each end of the scion, both cuts on the same side. A second cut is made on back side. The bark on both upper and lower sides of the wounded area is loosened as in bark grafting, and the scions are then inserted between the bark and wood of the stock and are nailed down. All cut surfaces are carefully coated with wax, and any sprouting on scion surface should be removed. Complete healing takes place in a few years.

Grafting Technique

T-Grafting

             
   In this technique, the scion wood is prepared as for veneer grafting. The shape of the cut on the stock is, however, different from that made for veneer grafting. A ‘T’ shaped cut is made in the stock bark, into which the scion is inserted and firmly wrapped with waxed tape. The graft is covered with polythene.

Grafting Method - Inarching or Approach Grafting

Image
Inarching or Approach Grafting Unlike other grafting operations, in inarching the scion is attached to the stock while it is still attached to the parent plant. Round the world, the method has been extensively used in the vegetative propagation of mango. The method involves potting healthy one-year- old seedling in earthen pots, which are usually 12 in deep and 8 in wide at the top. The earth ball along with root system is kept intact and placed in the pot. The unfilled space in the pot is then filled with a mixture of well- rotted manure and canal silt. The soil is firmly pressed around the earth ball and the transplanted seedlings are then watered. Potting of seedlings is usually done one month ahead of actual inarching operations. This allows sufficient time for the seedlings to set before grafting. Inarching can either be done in the spring months or in the rainy season. July and August are preferred over the spring season because after inarching operations in the spr...

Green Manuring

Image
Green Manuring A growing crop that is plowed under and mixed with soil to enrich the organic matter is called green manure crop. The practice of plowing under or soil incorporation of such green manure is called green manuring. Green manures are mostly leguminous crops which are high in nitrogen contents. Generally following crops are suitable for green manuring: Jantar, Guara, Cow peas, Alfalfa, Sun hemp and Clover etc. Criteria for the selection of green manure crops It should be fast growing and easily established. It should produce abundant and succulent biomass. It should be well adapted to the local conditions. Growth habit of crop should encourage ground cover soon after its establishment. It should be able to fix nitrogen in the soil. It should have a wide climatic and soil adaptation and ability to grow on poor soil. Advantages Improves the soil fertility Adds nutrients and organic matter to the soil Improves the soil structure Improves soil aer...

Basic Process of Soil Genesis

Basic Process of Soil Genesis During soil formation, the unconsolidated weathered material under goes many changes. These changes are brought about by variations in the four basic soil forming processes. Time required for a soil to develop the distinct layers (horizons). Horizons tend to develop more rapidly under warm, humid and forested conditions where there is enough water to move clay, humus and other colloids downward. Under ideal conditions recognisable soil profile may develop within 200 years and under less favourable conditions the time may extend to several thousand years. These four basic processes often referred as soil forming or pedogenic processes. They are responsible of soil genesis under all kind of environments. Addition                 Inputs of materials to the developing soil profile from outside sources are considered additions. For example, fallen plant leaves, dust, twigs, animal ...
