Kiwi bagging technical measures include: selection of bags, fruit thinning, fruit setting, spraying, fruit set, protection, and bag removal.
The choice of paper bag is a single layer of beige thin wax wood pulp paper bag, 15-18 cm long, 11-13 cm wide, open seam in the middle, plus wire on one side, and 2 to 4 cm on the lower corner, waterproof paper bag Good ventilation and good toughness.
The thinning of the kiwifruit in the dormant short shoots was used to maintain the fruiting branches, leaving 3 to 4 fruit pieces in each fruiting branch and removing excess fruits. The kiwi fruit pruned with long shoots was used to remove the fruits on the branches with weaker results at the base of the mother twigs. The remaining fruits were left with 2 or 3 fruits. As a result, the middle part of the mother branch can not be used to draw the resulting branch, and 3 to 4 fruits can be left on the sparse result branch. If the tree is weak or injured, the mother branch should be left with little or no fruit. Sparse pests, malformed fruit, grinding spots and malnutrition. When the fruit is thinned, the first is the inner and outer, and the weak branch is the first. The young orchard trees are strong or weak according to the results. Each result mother tree leaves 2 to 3 result branches, and each result branch leaves 2 to 3 fruits.
Spraying Control Before spraying the fruit, the whole garden sprayed an insecticidal bactericide, which can spray 20% of the sweeping 2500 times, 18% of the front kill 2000 times, or 2000 times of the green time, thiophanate-methyl or multi-bacteria. Ling and other broad-spectrum fungicides, control beetles, small salamanders, cockroaches, scale insects and other pests, control fruit soft rot, gray mold and other diseases. It is forbidden to use highly toxic and high residue pesticides and to control the use of plant growth regulators.
Bagging time The kiwifruit had the fastest fruit growth after 40 days of flowering, and the bagging time was appropriate around the end of June. However, it must be selected after spraying. When the sun is exposed in one day, it can be in the morning from 8 to 12 o'clock and from 3 to 7 o'clock in the afternoon.
Bagging method When bagging, open the bag mouth with one hand and put the good young fruit into the bag from bottom to top. The other hand will fold the bag mouth from the slit to form a uniform fold, and use the iron wire on the side of the bag. The folds are tied tightly. The result is that the single fruit on the branch can be directly tied to the fruiting branch. The bunched fruit is directly tied on the pedicel. The folded fruit bag is creased on the pedicel and can not be sprained. Or tie the handle. Check if the bottom of the fruit bag is open. If the bottom of the bag is completely closed, use scissors to cut the 2 to 4 cm opening. The upper seal is tight. When bagging, first inside and outside, the action is gentle, and the sagging or standing bagging branches should be fixed in time to prevent the wind from blowing.
After the nesting management, the management of fertilizer and water should be strengthened. After bagging, top dressing can be applied topically and foliar fertilizers can be sprayed to pay attention to irrigation and drainage. Strengthen summer pruning, cultivate enough vegetative branches and protect the leaf curtain layer. Strengthen integrated pest management. Timely stability of the frame, tied branches in time, wind and solid tree.
After the bags are harvested, the bags can be harvested after they are ripe. Remove the paper bag 3 to 5 days before fruit picking. The fruit bags that are tied to the result sticks first support the bottom of the fruit bags, loosen the zhaske of the fruit bags, and rotate the fruit bags and fruit bags to take off the fruits together. The fruit tied to the handle can pull the bottom of the fruit bag to rotate, and the fruit bag can be taken off together. Picked bags are gently removed and then graded.
