Pear Tree Dormant Prune Don't Miss

The pear tree enters the dormancy period and is a great opportunity for winter cutting. The winter pruning of pear trees is the pruning of pear trees after they are defoliated and before germination. Its main purpose is to cultivate tree shape, adjust the structure of the crown, cultivate the result branches, adjust the amount of flower buds, adjust the quality and quantity of branches, promote ventilation, transmit light, and rejuvenate. Canopy, continuation of aging, to achieve growth, balance of results and stable yield and high yield, lay the foundation for high yields. The trimming techniques of different ages are as follows:

Sapling trimming: The purpose of trimming is to shape the whole body, cultivate a good skeleton, promote branching, and promote early results. Generally adopt long-branch light shear and slow release, flatten the upright and strong branches, keep the short and middle branches, use the extracted shoots as much as possible, and expand the canopy. Except for sparse shearing of the dense branches, sparse shearing is generally not performed. The main branches and sub-main branches of the dense branches, thin branches, pests and branches and all disturbing the tree cut off. Long-branches and short-cut cultures are the result of branches; medium and short branches are those with strong shears and weak ones are placed slowly; small-angle branches are supported, pulled, and suspended to expand branching angles, ease the top growth advantage, and promote the early formation of flower buds. .

Fruit pruning: The main purpose of pruning is to control the growth of the tree, control the tree within a predetermined range, and keep the tree crown unshaded so as to facilitate ventilation and light transmission, maintain a robust and stable golden mean tree, and extend the fruit period. . For plants with vigorous tree vigor, it is necessary to control prosperous growth, remove more rot, cut short, cut branches to stand upright branches, leave more flower buds, and press the tree vigor so that it tends to moderate tree vigor; the tree vigor is weaker. The plants adopt heavier pruning methods to cut the strong branches and sparse the weak branches; take a short cut to some middle and short fruit branches, remove some of the flower buds, change the result branches into vegetative branches, and increase the proportion of vegetative branches; For stable plants, the focus is on the trimming of the resulting branches; for pears with a large number of flowers, cut off the inferior flower buds, shorten the flowering branches, and adjust the proportion of the resulting branches and vegetative branches.

Aging pruning: According to the degree of aging, carry out different amounts of pruning. The aim of this period of pruning is to restore the tree potential, rejuvenate the branches, and extend the results of years. Retract the pendulous perennial branches, and select the good back branches for the retracted parts. When the head sticks should grow strong buds, make them grow upwards, cut off some flower buds, and remove weak branches. Try to make use of leggy branches to fill incomplete canopies, restore vigor, and regain high yields. Severely aged trees saw the canopy, leaving only the main lateral branch skeleton, promoting the germination of the bud, recultivating the canopy, and restoring production. For the transformation of aging trees, it is necessary to strengthen the management of fertilizer and water and pest control.

Double Packed Yellow Waxy Corn Cob

The most common waxy and sweet corn market, waxy corn nutrient content is higher than ordinary corn, contains 70-75% starch (and almost all amylose), more than 10% protein, 4-5% fat and 2% multivitamin, has more grain, VA, VB1, VB2 than rice protein, fat and VB2 highest content. Yellow corn also contains carotenoids like rice and wheat. The molecular weight of glutinous corn starch is more than 10 times smaller than that of ordinary corn. The starch makes glutinous rice sticky and soft, which is softer than that of ordinary hard corn. It has more than 20 percent more digestibility than regular corn and is suitable for people with irregular teeth. At the same time, the amylose (a polysaccharide) content is very high, not suitable for diabetics.

Waxy corn is also called sticky corn. The grain has a coarse, waxy endosperm that resembles a glossy, transparent grain, such as a hard, dented corn. Its chemical and physical properties are controlled by a recessive gene located on chromosome 9. 100% of the starch in the endosperm is amylose.
